Cecil, You still don't get it.
I get what you said. Here it is again.

The only "phase" remaining is the cos (kz) term, which is really
an amplitude description, not a phase.
So you alluded to phase information in the standing wave
current amplitude.
When I said the phase information was gone, I meant it.
But you also said:

We know that there is phase information in the traveling waves.
So for your statement to be true, there has to be phase information
in the standing wave.
Both of your statements cannot be true. Which one are you
willing to stick with and which one are you going to retract?
If you look at: http://www.qsl.net/w5dxp/travstnd.GIF
you will see that the standing wave amplitude is indeed
a cosine function of the phase. Taking the arc-cosine
of the normalized amplitude yields the phase angle.
I'm sorry, but you have contradicted yourself a couple of times
so I don't know which assertion you want to go with.
Cecil,
I have not contradicted myself, and I have nothing to retract. Only in
your imagination is there any useful phase information in the traveling
waves that make up a standing wave. There can be other waves that don't
exactly balance out into a standing wave, but that is another topic.
I am not sure to whom the "we" refers in your statement, "We know that
there is phase information in the traveling waves." Perhaps that is the
Royal We, because it certainly does not include me. The phase
information you might find is of no use, and it is simply an artifact of
the mathematical analysis.
If the standing wave adequately and completely describes the
electromagnetic situation, then there is no additional available from an
arbitrary decomposition in traveling waves. If you try to look at the
traveling waves one at a time, then you are no longer considering a
standing wave.
