Coils and Transmission Lines.

Does your program take that into account? The "current through coils" argument boils down to the ones who understand standing wave currents in a standing wave antenna and those who refuse to take the time to understand. Quoting "Optics", by Hecht: "E(x,t) = 2Eo*sin(kx)*cos(wt) This is the equation for a STANDING or STATIONARY WAVE, as opposed to a traveling wave (Fig. 7.10). Its profile does not move through space. ... [The phase] doesn't rotate at all, and the resultant wave it represents doesn't progress through space - it's a standing wave." Until the gurus take the time to understand the nature of standing waves in standing waves antennas, they will keep committing the same mental blunders over and over. Hecht forgot to put the phase difference in his formula. It's no wonder there's no phase information in your standing waves, Cecil, Hecht left it out. Not only that, but where did he get the idea that it was sin(kx) instead of cos(kx). I understand Hecht is a good old boy, but I'd like to see his derivations. 73, Tom Donaly, KA6RUH |
