Forward and reflected EM waves, of course. Would you like to deny
the existence of the two waves in the following equation?
I(x,t) = I1*cos(kx+wt) + I2*cos(kx-wt) = Io*cos(kx)*cos(wt)
Your lack of math skills is really getting to be embarassing.
... can dismiss displacement currents as trivial things that can
be ignored when they are required to define the most important aspects
of transmission or antenna behavior,
The only displacement currents that I said were secondary were
the displacement currents to ground. In fact, in a shielded coax
with no common mode current, displacement currents to ground
are literally non-existent, yet the standing wave is still there
inside the coax, with its nodes and loops.
... and say the very thing that is
used to measure current suddenly doesn't measure his imaginary two-way
reflected and forward current's vector sum.
I didn't say that. I said the standing wave phase cannot be used
to measure the phase through a wire or a coil. That is readily
apparent at: http://www.qsl.net/w5dxp/travstnd.GIF which you
have been avoiding like the plague.
The phase information is there in the standing wave current, but
it is in the magnitude, not the phase. And you have to understand
arc-cosine functions to be able to extract that phase information.
That's what is really important, especially in light of the fact Cecil
is quick to play superior.
"Play superior"??? I'm not the arrogant one claiming to be so
omniscient that he is never wrong.
Anyone who is really superior should be able to walk us through the
physics of two-way current ...
Already done - please reference the above web page. All the data
is exactly what EZNEC reported. I can lead you to water but I
can't make you drink. If you will tell me what you don't understand
about that web page, I will walk you through it, step by step.
