What is the ratio of magnetic electrons emitted from a radiator
compared with with the number of electrons emmitted due to current flow? What is the combination ratio required of both types of electrons to form a radiation field? Regards Art |

Hi Dave, All electrons are magnetic. All electrons flow in current. Electrons emmitted (sic) would first have to be accelerated by a potential that exceeds the work function of the metal they inhabit, and then avoid the resistance to their movement found outside that metal. This is called induction current. Emission, except in a vacuum, is considered to be a nuisance as it causes havoc in the vicinity (such as superheating air to luminescence). There would be electrons of emission only in the first few micrometers from the conductor (not sure why that would be of any particular advantage). Of course, all such terms and their usages are conventional. Their usage and application in this thread probably have meanings that deviate wildly from the norms of accepted usage. 73's Richard Clark, KB7QHC |

What is emitted from an antenna is primarily photons. Each photon has both electric and magnetic properties and the ratio is 377 ohms in the far field. -- 73, Cecil http://www.w5dxp.com |

"What is the combination ratio required of both types of electrons to form a radiation field?" A company called Tigertek, Inc. answers questions such as this. Art can search on "amateur radio fact of the day from Tigertek" and their pages should appear. Click on "Facts of the Day, Software and Forums". Select "November 26, and see: "Electromagnetic E/H Ratio". Click and find: "----at a distance of several wavelengths or more from any type of electromagnetic radiator the ratio of electric to magnetic field strength (E/H) always becomes equal to approximately 377 ohms, which is the approximate electromagnetic impedance of space." Jan 3: Electron Facts July 29: Does Your Antenna Radiate Particles? "----Unlike protons and neutrons, photons have zero rest mass. (Albert Einstein`s special relativity theory predicted that massless particles travel at the speed of light in a vacuum.) Furthermore, unlike protons and neutrons which are composed of smaller particles called quarks that are bound together with massless smaller particles called gluons, photons (and electrons) are elemental particles that are not composed of smaller particles. Transmitting antennas do indeed radiate particles." Best regards, Richard Harrison, KB5WZI |

It should be added that "particles" accelerated to the speed of light (radiation) have infinite mass requiring infinite energy to get them there. Particles with non zero rest mass, that is. |

Ahhh come on guys, and Art, , get a grip...
Electrons are 'emitted' from the surface of a conductor only under specific circumstances, such as the Photoelectric Effect, in a direct electric arc such as an arc welder, off the hot surface of a filament, off the cathode of an electroplating device, etc.... All of these are mass events where the departing electrons will in time change/erode the surface material of the emitter... Electrons do not normally depart the surface of an RF antenna; local corona discharge, or mechanical short circuit, or electric arc, being the main exceptions and are not germain to the intended purpose of the RF antenna.. The antenna surface is not eroded or mass altered by the long term emission of electromagetic waves because no electrons are being launched/emitted off the surface res ipsa loquitor... OK, now back to the regularily scheduled reruns of Howdy Doody you can learn a lot from these denny / k8do |

Is that because the departing electrons leave "holes" in the conductor atoms? :-) -- 73, Cecil http://www.w5dxp.com |

OK, now back to the regularily scheduled reruns of Howdy Doody you can learn a lot from these denny / k8do Denny, I believe you are correct that what is known as basic physics does not have universal consensus in this group which is not all that bad because we are all amateurs.I know that mass is not constant in itself since it is always self adjusting to maintain equilibrium. It would also appear that what is emitted is so small and numourous that it can be seen as a cloud or a field. I also believe there is some sort of consensus that these two clouds are still somewhat homogenous after they have escaped from the initial gravitational forcesi.e merging of these entities is achieved beyond the arbitary border. Some have gone off at a tangent by introducing 377 ohms as a ratio which ofcourse is an impossibility which destoys the credability of their whole statement. At the back of my mind I was trying to determine how the makeup of skin depth occurs since at a moment in time the surface of the conductor is seen as composed entirely of static particles and what changes occur when the material conducts since the surface is totally boundduring the radiation process. So Tom this is a good time to bow out, since once again on this group we have encountered a situation where actual knoweledge is piece meal at best and where continuation could only introduce falacies to the subject. One thing I am assured of is that despite claims offered this is by no means BASIC physics theory but a collection of fragmentary knoweledge which could easily evolve in what is termed junk science as the many opinions merge. Gentlemen have a great day and try to concentrate on the beginnings that Gauss has now provided us by the addition of the metric of time and formulate a theory within that context since it presents an avenue of new additional information.than that previously known.
