Szczepan Bialek wrote: "This is usually a large conductor attached to one side of the power supply (such as the "ground plane" on a printed circuit board) " The "large conductor" works as the earth. S* So you agree that a transmitter needs no connection to the earth? Of course YES. The "large conductor" is enough. There is no "large conductor" on many modern circuit boards so you are wrong yet again. Hello jimp. Pity he can't define "large" or understand "ground". |

Anyone understand what Szczepan means by "oscillatory electron flow", please? I'm assuming he means a sine wave or a push-pull current. It has no conventional meaning. He probably found the phrase in some speculative writtings of someone who has been dead for at least 100 years. |

Electron waves travel. No doubt, and please give an example of an electron wave. One more time. It is impossible for electrons to travel at the speed of light. But RF EM waves travel at the speed of light. Therefore, it is impossible for RF waves to consist of electrons. Electrons act as a bucket brigade for "buckets" of photons. -- 73, Cecil, w5dxp.com |

And what about the "displacement current? If Maxwell had known about photons, he would never have invented displacement current. Assume we have an ideal transmission line terminated in an ideal capacitor with two plates. It's easy to prove that the displacement current flowing from one plate back up the transmission line, through the source, back down the transmission line onto the other capacitor plate has to be traveling much faster than the speed of light. Does that give anyone pause to question the very existence of "displacement current" in reality? -- 73, Cecil, w5dxp.com |

Back when physicists and engineers were ignorant of the existence of photons, that was the best they could do to explain electromagnetic fields surrounding free electrons being energized by AC signals. Nowadays, we know that at RF, the electrons oscillate virtually in place and it is the photons that are responsible for energy transfer (flow). -- 73, Cecil, w5dxp.com |

There are no "Electron waves". Probably not in ham radio but a single electron exhibits the same wave behavior as a photon in double-slit experiments, i.e. a single electron seems to go through both slits and interfere with itself on the other side. That is wave behavior. Strangely enough, a single very large Buckyball exhibits similar wave behavior. -- 73, Cecil, w5dxp.com |

A particle may have some wave properties but that does not make it a wave. |

Back when physicists and engineers were ignorant of the existence of photons, that was the best they could do to explain electromagnetic fields surrounding free electrons being energized by AC signals. Nowadays, we know that at RF, the electrons oscillate virtually in place Each of them is in small fixed box and oscillate? and it is the photons that are responsible for energy transfer (flow). Each waves transport mass and energy. The oscillations are not simmetrical. S* |

On many modern circuit boards there is no large conductor. You are a babbling idiot. Not me but the Autor of Wiki. S* |
