Nonsense. All it takes is two identical waves traveling in
opposite directions along the same path. Such happens at the
open-circuit or short-circuit point in a 1/4WL stub.

Here we have an excellent illustration of the kink in your understanding
of wave phenomena. Because just as interference does not cause waves to
reflect, waves do not make other waves do things, or turn into something
else. A standing wave interference pattern is a result of the presence
of traveling waves. One does not replace the other.

I urge you to please investigate the mathematical issues associated
with summing counter-rotating vectors.

I have, Jim. It is you who seems confused. If two coherent
phasors of equal amplitudes and opposite rotations are
phasor-added, the resulting total phase is a constant.
1 at zero deg + 1 at zero deg = 2 at zero deg
1 at 45 deg + 1 at -45 deg = 1.4.4 at zero deg
etc.

I you were producing numbers which made sense and were correct, we
wouldn't be having this discussion, Cecil. A wave is at various phases
along it's length. The phase varies from 0 to 360 every complete cycle.
This includes standing waves. Its phase is not "zero" at every point.
It's ridiculous to have to point this out to a self proclaimed "expert"
on any and every subject such as yourself.

Correct me if I'm wrong, but as far as I know you are the only one
suggesting that standing wave current phase - whatever that is - could
be delayed, measured, and calculated.

Nonsense, Jim, standing wave current phase is what EZNEC
reports for a standing-wave antenna.

In my experience, incorrect assumptions produce incorrect results. The
EZNEC results you refer to are an archetypal example of the effect.
