The vector calculus describe only movements. Really? I did not know that. Crap. And argh. I thought it was more useful than that. Who knew? tom K0TAR |

Since your model supposes that the "plasma" carries the signal, what does the model predict as the radiation resistance of a dipole in free space? Given your model, which you have spoken about at some length but no depth, why wouldn't your predicted radiation resistance change with plasma density, contrary to all measurements ever made? tom K0TAR |

S* Where did Cecil mention "coherence"? Photons and incoherence are the same. "In 1900, Max Planck was working on black-body radiation and suggested that the energy in electromagnetic waves could only be released in "packets" of energy". In a black body is many dipoles which work with brakes. In radio a dipole (or monopole) works continously. S* |

Molecules are the medium for acoustic and free electrpns for the electric waves. S* |

It is not my model but Tesla's. Probably he was spoken deeper. You try to marry Heaviside with Tesla. TEM are not longitudinal. Longitudinal waves have analogy with acoustic waves. S* tom K0TAR |
