You get exactly the same answers doing it my way but my way yields the additional information of exactly what happens to the energy components. When two wavefronts superpose to zero indefinitely, I would take that as proof of interaction and wave cancellation. This is what invariably happens to the discussion. After being told that I am absolutely wrong about energy flow, I introduce the known laws of EM physics from the field of optics and prove that they provide exactly the same answers as a conventional RF analysis. After some discussion, it is asserted that the person (not only you) doesn't care and it doesn't matter anyway. W7EL says in his food-for-thought article, "I personally don’t have a compulsion to understand where this power 'goes'." hams 'know' where the power goes, their swr meter tells them it goes back to the transmitter! why don't physicists working in optics calculate fields? the electric and magnetic field models work just as well at those frequencies as they do on hf. indeed, why don't optical physicists learn something from rf designers and model their thin films with transmission lines! |
