The nature of traveling wave current and standing wave current
is different. 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.
