I agree with you but W8JI and W7EL have rejected the concept that
there is any phase information in the standing wave current magnitude.
They have rejected any use of the arc-cosine function in calculating
that phase. The following graphs show the difference in the standing
wave current and the traveling wave current.

Egad. Of course I reject the notion that there's "phase information in
the standing wave current magnitude". Magnitude and phase are
orthogonal. There's no phase in the magnitude and no magnitude in the
phase. There's no real portion of the imaginary part and no imaginary
portion of the real part. I haven't a clue what you mean by "use of the
arc-cosine,function to calculate that phase", but I certainly reject any
method that assigns a phase value to a magnitude or vice versa. I get
the total voltage or current simply by adding the traveling waves. No
trig functions necessary, just simple vector addition.

Traveling waves have phase information. In a steady state system they
can be expressed as phasors, which consist of a magnitude, a time phase
reference value, and an implicit time varying time rotation. When you
add them to get the total (which Cecil likes to characterize as a
standing wave as though it's something different than just the total
voltage or current), you get the simple vector sum of the constituent
traveling waves. This sum is also a phasor, with magnitude, time phase
reference value, and the same implicit time varying phase rotation.

In summary, both traveling waves and the total voltage or current are
phasors, and both have phase.

What's so complicated about adding a couple of phasors? Cecil, you need
to go back and read, and understand, your freshman circuit analysis text.

What a bunch of irrational smoke and mirrors.

I don't care less what Cecil will make of this. But Gene, do you really
disagree with what I've just said?
