Maybe your browser is different the term wiki or wilki may provide a clue as to the browser I used Jim you are starting to get very rude, I never said that Vlasov- Maxwell had anything to do with antennas |

Hello, and I would like to propose that subjects in the area of general
electromagnetics be posted to a more appropriate ng such as sci.physics.electromagnetics or sci.physics.research (moderated). I think Mr. Unwin has a better chance of finding more sympathetic ears to his propositions in a more theoretical venue. Along with that recommendation goes a quote from the late Carl Sagan: "Extraordinary claims require extraordinary proof."

Ask your children for help or maybe somebody in the group will come forward to help you. Don't know why you are following the thread it is all blabber. Can';t you block me? Wikianswers statement referred to The question raised was that Maxwells laws require equilibrium Full wave antennas are in equilibrium buf fractional wavelengths are not. ((((((((!!!!!( Seems like I have heard that a lot on this newsgroup )))))!!!!!~ The answer was basically in agreement and stated that for fractional wavelength antennas requires compromises when applying Maxwell laws.. You can now ask where the curfrent goes when it reaches the end of a fractional wavelength radiatorand get what some say "is the rest of the story" On the other side you can bombard Wilkianswers that HAM RADIO REJECT the idea of associating equilibrium with Maxwells laws or any other laws in Physics.as it just blabber and does NOT represent the present day thinking of ham radio enthusiasts in the U.S.and the American Navy reseach centers in Washington DC You, the experts, can also ask the ARRL to print same in QST otherwise change will become unstopable Regards Art |

You can now ask where the current goes when it reaches the end of a
fractional wavelength radiator and get what some say "is the rest of the story". Current is always zero at the end of a radiator of any length. Frank |

Current is always zero at the end of a radiator of any length. Frank Maybe Frank but it never came to a stop!!!!. When you look at it as not being equilibrium one must show the sharges moving to the ends of the radiator where end effect is created. Now you draw a line to the right on the outside of the radiator with an arrow at the end to show the movement of the charge. Now the original notion that there is no charge or current goes away because a reactive line and arrow must be assigned for quasi equilibrium to be established and that line or vector has only the center of the radiator to flow to form a closed circuit. When a radiator is in equilibrium the charge does NOT move to the end so that there is no vector to the right thus physics state that the need for an opposing vector does not exist. Thus for a radiator in equilibrium current will move along the surface but the charges will not. So do the charges really stay in a static possition? No it doesn't It was on the surface over the skin provided by the eddy current which when combined with moving current both produce a combination magnetic field that provides a vector force away from the surface of the radiator. The charge static position.is thus over powered by the combination magnetic field that places a spin upon the partiucle and ejects it in a straight line trajectory. These ejections have a reberatory effect on the radiator and also on the receiving radiator so that communication occurs in a vibratory manner Now the extension of gaussian static field shows up in actual radiation phenomina in the same way the eddy current fields provide levitation which thus agrees with other known laws Tho it can be shown that the law of statics is part of Maxwells laws mathematically I know of no disclosure where the same was approached from a strictly flux flow position which brings static particles into the mode of radiation as well as defining the eddy current creating the "weak" force as anticipated by Einstein till he died.Nowhere is a physics law violated physics laws have been solidified and the theory is solid Best regards Art Unwin.....KB9MZ........XG |

We deal with sinusoidal waves because all other shapes can be nade from combinations of these. Particle aspects of radiation come to the fore only when radiation interaxts with matter. Physics tells us a particle that moves with constant momentum in a straight line according to Newton`s first law (inertia statement) has wave motion, according to the "de Broglie hypothesis". Lambda = Planck`s constant / momentum. The wave aspect of EM radiation is used as a model to make the phenomenon intelligible in terms of familiar laws and events of our everyday, large-scale world. The 3rd edition of Kraus` "Antennas" says on page 904: "They (computer program designers) could develop software to simulate the performance of antennas. In general, these techniques either numerically solve Maxwell`s equations by descretizing the problem using integral techniques, such as Moment Methods (MoM) as discussed in Sec.14-11, or differential technuques, such as finite elements or finite difference-time domain." Maxwell gave us everything we need. Best regards, Richard Harrison, KB5WZI Again you are misquoting and this time it is Planck His constant evolved around a proton where the results has some conflicts to this day with respect to classical science. When he was studying black holes in the aether he saw it as PROTONS escaping and not particles such as neutrinos which have since proven to have mass where he was using the term momentum which is a varient of mass and gravitational effects. There is nothing that suggests that energy can be carried without the presence of mass and thus the wave of energy as inferred by many is debunked, Yes Maxwell left a lot but he nevver alluded to static particles and piossibly not even to the pre condition pf equilibrium. What he is famous for is noting all the observations and equations of his predecessors and used his mathematical acumen to reduce or condense the laws given to him of which he did not individually contribute as personal observations at that particular time. Gauss specifically mentioned static particles where Maxwell omitted such references thus leaving radiation as a mystery where the "wave" format gained strength because of the magnetic field format b ut with which Einstein disagreed. Einsteins foray into relativity further debunked the idea of waves or energy without mass to carry potential energy or to show the effects of kinetic energy and the association between gravity and momentum and the importance of frequency of movement. You cannot rely on the forever continuance of old books that were used in your part of the centuries as being imbedded in stone based on your own particular life span.History shows that new generations come along using the education of their fore fathers on whose shoulders they stand and where the human race requires challenge that the past may or may not accept when their time comes about and thoughts go with them. Remember a constant as used by Planck is purely a mathematical condition which describes an event that occurrs physically without change such that a number can be prented in the place of a full description of the actual event in a similar way the "wek force" has been calculatedf for the past century.

Frank Maybe Frank but it never came to a stop!!!!. When you look at it as not being equilibrium one must show the sharges moving to the ends of the radiator The charges (electrons) do not realy move. They vibrate at the applied E-field frequency. The charge displacement, depending on frequency; for example at 10 MHz, is of the order of 10 atomic diameters -- approximately 2*10^(-9) m. http://www.geocities.com/ferman30/AtomsDimTable.html Frank |
