Acceleration of the particle only occurs while within the electrostatic field. When it exits it has the speed of light because it has emmerged from the intersecting two fields.and thus from *the accellerating forces. I remind you of Newtons law of ut + 1/2 ft sqd The first expression is for the speed attained on entering the accelerating field and the other half is for the length of the accelerating electrostatic field. On leaving the two fields it looses the applied accelerating force where it has arrived at a particular speed.Maybe you should look up the workings of a CRT using Newtons laws instead of shooting from the hip. It was at a different time that the speed of light was measured where it was found to equal the sppeed emerging from two intersecting fields. * Actually, I'm well aware of the principle involved in accelerating electrons in an electron gun as used in CRTs, klystrons, TWTs, and so on, by subjecting an electron cloud to a potential difference using an anode with a hole in it (!), but that's different from what happens in an antenna. The acceleration of charge in an antenna results almost entirely from the applied potential difference at its terminals. *The radiated fields result from the alternating current effectively passing through the radiation resistance, and all the other, reactive, fields have no direct effect on the radiation resistance, or the component of the current that passes through it in phase with the voltage that is developed across it, which together, of course, represent the radiated power. *The reactive fields affect the terminal impedance and a large imaginary part can upset the device trying to send power into the antenna, but that is more of a system issue. *The alternating current that passes through the radiation resistance is composed of charge that moves in time with each RF cycle, accelerating and decelerating accordingly. *The electrostatic field developed between the ends of a half-wave dipole reaches its maximum value a quarter of a cycle later than the voltage at the drive point so any effect it has on the charge in the antenna elements during each cycle must be reactive, and it doesn't affect the radiation resistance or the radiated wave. But all this can be looked up from any one of the respected books on antennas. *Krauss, and others, gives expressions for the different field components and the theory all hangs together quite readily using Maxwell's equations without modification. I don't care if you think me stupid, and I'll continue to try to avoid name calling of individuals, although I may criticise what they write especially if it appears ignorant of proper science yet attempts to re-write established theory, and therefore appears arrogant. Chris No it does not appear in Kraus book. He never followed Maxwells laws with respect to equilibrium. To do that you must think in terms of wavelength. After all with respect to science all revolve around boundary laws of the Universe and you blindly ignore that fact. Now back to radiation which applies spin to a p. Nowarticle where as with a crt no spin is applied as it is heat that separates the resting particle Now earlier you refered to a electrostatic field that according to what you stated did not have a border and surely you know that just can't be unless it is in equilibrium which requires a closed circuit. For this to come to fruition you go back to the boundary laws where the arbitrary border is one that is closed i.e. in equilibrium. Now cast your mind back to the Gauss extension where radiators and particles lie in a closed static field. Now you should see that equilibrium must reign for a closed static field. Now you blithely mentioned an electrostatic field with nary a mention as to how it is formed and how it fits into the whole picture. Why? Because the books do not provide an unbroken trail that fully describes radiation ( books admit that) as I have done where everything dove tails into the existing laws of the Universe. And then I gave you a bonus with respect to the weak field that Einstein searched for in vain. Einstein looked at the package presented by the Big Bag but omitted to keep that which it was wrapped into. That was the arbitrary boundary around which were forces or vectors that were equal and opposite when a smallest of smallest of particles edged out towards the border. Yes it was of a weak force but for all of that it broke the equilibrium boundary as the forces at that point was not now equal. The breakage was one where the opposing forces were offset to each other thus providing a torque force that provided spin. Now we come to our own Earth encased in a arbitrary border and outside the border we have the same conditions of equilibrium that must equal the forces of the Big Bang which means the outside has two vectors, gravity vector which is straight and a vector denoting spin i.e. rotation of the Earth. On the other side of the border you again have two vectors a straight vector and that curly one you don't like me to call eddy current. Yup. Everything falls together nicely thank you, when you study radiation from first principles instead of binding yourself to books that readily admit to not understanding the radiation process. Now this is not being arrogant when one has applied all principles but I do think it is arrogant of you and others to asasinate the character of "S" purely because of his english and spelling and not to help one that wants to learn. Just think about it all. I have shown how a particle moves in space in a straight line trajectory such that the particle maintains a straight line without the parabolic force of gravity driving it down to the Earth. Go back to your books and show just how the electrostatic field came about and what was the borders that it was contained in Art via applied spin and where gravity |

You are talking garbage Tom in a attempt to sound educated. When you introduce Newtons laws you are standing on the existence of mass. It was a particle with mass that broke the equilibrium of the Sun which starts the whole cycle. This mass is debris from the burning and release of energy from the sun which ebbs and flows according to the 11 year sun spot cycle. It is acknowledged that particles from the Universe are in the billions per cubic meter in the Earths system and all these particles have mass. The idea that neutrinos, a particle from the Sun had no mass was dispelled years ago, so the Laws of Newton remains in place. This very same action is shown with respect to a CRT where the particle which in that case does not have spin. You will see that the particle is accelerated within the borders of the electrostatic field which is also intersected by a mgnetic field such that its path is parabolic within the confines of the electrostatic field which becomes a straight line travel without acelleration as it leaves the confines of the electrostatic field. It is all quite simple Tom but you continue to implant erronius data into the description as a basis to supply insults. Have you now discovered a new particle which has charge and no mass? There you go again, all particles have mass and Newtons laws are still in place Stop playing the fool tom K0TAR |

At the open circuit in the wire, all the energy in the wave is transferred to the electric field. " S* What Richard wrote is correct, if written in a slightly provocative manner (deliberately?). But he wasn't stating that the electric field 'At the open-circuited ends of a resonant antenna' passes energy into a radiated radio wave. Look at this: ""At the open circuited ends of a resonant antenna there is almost double the forward voltage". "Almost double voltage" is like the pressure in the Kundt's tube. The energy that makes it that far (i.e. isn't radiated on account of current in the element) is stored temporarily in an 'electrostatic' field which is one of several 'reactive' or 'induction' field components that surround a dipole antenna and decay with distance much faster than the radiation field components (i.e. those that make up a radio wave). As I've noted before, the term 'electrostatic' should not be interpreted literally as an unchanging field - it is used to differentiate between the reactive components and the radiation components of electric field - if this offends you, just call it a 'reactive' component of electric field. This stored energy is passed back into the antenna during the following RF quarter cycle. And guess what ... one of the reactive field components is longitudinal! ... but it isn't part of a radio wave - both parts of a radio wave, the magnetic field and the attendant electric field, are directed transverse to the direction of propagation, but now I'm repeating myself from a week or more ago. Power cannot be abstracted from the reactive fields, including the longitudinal one; they affect the imaginary part of the terminal impedance of the antenna. Of course, I expect you will contradict all this but I still recommend that you read a proper account of the fields around a dipole rather than making up your own version. It is not my version. The electrons were discovered 100 years ago. Since you appear to have a phobia of libraries, you could buy a second-hand copy of Kraus, Antennas for only $15 online: http://www.abebooks.com/servlet/Sear...nnas&x=55&y=10 and there are many, many other sources.

Without that it was be impossible to know that Maxwell proposed the displacement current to save the incompressible electric fluid. In Maxwell times AC current was known. To pass the incompressible fluid through a capacitor the displacement current is necessary. I prefere the compressible electrons. They compress in the plates and nothing flow between them. The polarization is not the macro flow. and yes, richard's statements are true, but a bit too restrictive, it doesn't HAVE to be resonant. Voltage doubles and current=0 at the end of any wire fed with a time varying current, it doesn't even have to be a sine wave... note the effect of sending square waves from a time domain reflectometer down an open circuited wire.

What they are doing is using you for cannon fodder. Day after day they state the new for me aguments that the acoustic analogy is the winner. Try looking at things my way. You know that when a time varying current is applied to a radiator that it also supports a reacting current with spin, known as as an Eddy current You also know that the current applied produces a electrical field and a magnetic field that interchange energy between each other in the form of a tank circuit. You go into details. Now is not time for that. Now we should work out the consensus on which part of the radiator radiate the radio waves. Now look at the sequence of actions.We do know that the Eddy current produces a lifting force and a spin force and we also know that there is a electro static field surrounding the radiator. First we must recognise that particles encapsulate the whole radiator but can be individually lifted from the radiator with spin applied a short distance. At this point it enters the electrostatic field around the radiator where at the same time the generated magnetic field is intersecting the electrostatic field. The moment that the lifted particle enters the electro static field mix it is subjected to a accelarating force exactly the same way as a electron in a CRT is impacted upon. If you refer to the actions within a electron tube you will note that the electrostatic field offsets the direction of the accellerated particle into an exiting parabolic direction. The combined fields will only accelerate the particle while it is within the electrostatic field proper, after which it has a straight line projection with spin. The time that it is within the electrostatic field is the total accelerating time ie Newtons law 1/2 ft sqd. The acceleration imparted to the particle happens to be the speed of light which implies that this particle is able to emit light. If you have difficulty then read up on the CRT. As a point of interest the Eddy current itself must be balanced by an equal and opposite force per Newton and if we look at it in boundary terms we see that the opposing force is the combination of Gravity and the rotation of the Earth. What this shows is that the particle has spin and accelleration where the vector associated with Gravity is now neutralized such that it retains its straight line action with spin as it traverses the boundaries of the Earth Another thing of importance is that Newtons laws are based on the condition of mass where the particle becomes an excellent fit as opposed to a field or a wave. Back to the radiator itself. If it is a full wave length then it is a closed circuit of the tank circuit form. If a radiator is less than a wave length then yes, charges will form at the end of a radiator but is hampered from further movement by the opposing impedance of the environment. The charges will still leak but with out a spinning action it will remain in the near field. Ofcourse changing the environment will give an instantaneus charge in a spark form because as an open circuit it always searches for the closed circuit function. It will not be easy to work out here all details. S* Regards Art |

Yes. But antennas are in resonance. That is rarely true. A naturally resonant antenna has zero reactance at its feedpoint. But that is not a requirement for it to produce EM radiation efficiently from all of the r-f current flowing on it. The monopoles used by MW broadcast stations vary from 60 to 225 electrical degrees in height. Only a few of those heights are naturally resonant. Yet they all radiate nearly 100% of the applied power, because any antenna reactance is offset by an impedance matching network at the feedpoint. RF |

The same thing happens with an open-circuit stub yet it radiates a negligible amount. The only place where an antenna radiates more than a negligible amount is where the forward and reverse currents are unbalanced. At the ends of a 1/2WL dipole, the forward and reverse currents are perfectly balanced, i.e. they are 100% transmission line currents which are known not to radiate. At the 1/2WL dipole feedpoint, the forward and reverse currents are most unbalanced, i.e. since they are in phase at the feedpoint, they can be considered to be 100% antenna currents. This is just one more example of the illogic of forcing forward and reflected waves into a mashed potatoes theory of energy. The underlying laws of physics are lost in the process. -- 73, Cecil, IEEE, OOTC, http://www.w5dxp.com |

Far-field EM radiation is produced only by the current flow on the antenna, and that radiation contains BOTH the electric and the magnetic fields. You may have missed the accurate description posted by Chris, and pasted below. "The acceleration of charge in an antenna results almost entirely from the applied potential difference at its terminals. The radiated fields result from the alternating current effectively passing through the radiation resistance, and all the other, reactive, fields have no direct effect on the radiation resistance, or the component of the current that passes through it in phase with the voltage that is developed across it, which together, of course, represent the radiated power. The reactive fields affect the terminal impedance and a large imaginary part can upset the device trying to send power into the antenna, but that is more of a system issue. The alternating current that passes through the radiation resistance is composed of charge that moves in time with each RF cycle, accelerating and decelerating accordingly. The electrostatic field developed between the ends of a half-wave dipole reaches its maximum value a quarter of a cycle later than the voltage at the drive point so any effect it has on the charge in the antenna elements during each cycle must be reactive, and it doesn't affect the radiation resistance or the radiated wave."

Physicists may wish to take it further but there's no evidence of physicists in this newsgroup. And then I gave you a bonus with respect to the weak field that Einstein searched for in vain.

Yes it was of a weak force but for all of that it broke the equilibrium boundary as the forces at that point was not now equal. The breakage was one where the opposing forces were offset to each other thus providing a torque force that provided spin. Now we come to our own Earth encased in a arbitrary border and outside the border we have the same conditions of equilibrium that must equal the forces of the Big Bang which means the outside has two vectors, gravity vector which is straight and a vector denoting spin i.e. rotation of the Earth.

It's rather unfair to expose this only to an amateur radio newsgroup when what you are doing is apparently re-writing physics in such a major way.

Surprised you dont know that! Easily done. Boundary laws are based on Newtons laws where every action has an equal and opposite reaction. So a subject under discussion is placed inside an arbitrary border where the forces of the contents must be equal to the sum of the forces outside the boundary. Where does Krauss deviate from from Maxwells laws? well for one thing his radiator differed from a full WL or period so immediately he has strayed. Another thing is by straying from a full WL he was unable to contain the electrostatic field within a border such as a quad. And it goes on especially with regards to his windings pitch theory.

I am sharing it with industry and not the boneheads who bunch themselves into secret rooms away from those outside who cannot possibly provide anything of interest. They have the common interest that if it doesn't come from them..........!!!!!! Pretty much the same as this group. We shall see Art * OK, at an appropriate juncture I'll invite some of them to come over and take a look at what you write here (crossposting would probably be frowned upon). It might be enlightening to receive the views of some physicists. Chris |

Chris If you know of any I would welcome their views. There are many retired educated people in this world today that turn to that which they had an interest with when young. Now it is difficult to get up to speed in different sciences because various journals get the rights of various papers from Universities e.t.c which are then denied to libraries and the public. This is a resource the country should assist because its costs are low and where all have large experience obtained thru their working years. Imagine professionals who when retired have twenty or more years of experience be allowed to follow and contribute in areas where an interest has laid dormant for so long. Today's efforts are applied to computers where data comes out in bundles which have to be sorted to determine if anything good is being offered by using a mish mash of arithmetic formulae that are merged with similar formulae from different functions. Sad, sad, sad. |

Whether OE maintains the ''s before lines of quoted text seems to depend on something in the text I'm quoting. I gather it is a known issue, and it's the reason why I sometimes use a '*' before the first line of new paragraphs of my response. I have been told I should ditch OE but I don't want to use webmail; I could use Agent but I haven't so far. Chris I highly recommend Mozilla Thunderbird. Roy Lewallen, W7EL I second that recommendation. tom K0TAR |
