And, of course, you are showing your ignorance. Let's say that
at the current maximum point, the forward current is 0.5 at 0 deg
and the reflected current is 0.5 at 0 deg. The standing wave
current at the current maximum point is 1.0 at 0 deg just like
a cosine function is 1.0 at 0 deg.

Now let's go 45 degrees away from that current maximum point. The
forward current is 0.5 at -45 deg and the reflected current is
0.5 at +45 deg so the standing wave current is 0.707 at 0 deg.

The magnitude of the standing wave current is 0.707. The arc-
cosine of 0.707 is 45 degrees. Do you really and truly believe
that is just a coincidence? Exactly as Gene Fuller said previously,
there is phase information in the standing wave current magnitude.

Here's a quote from Gene:

Gene Fuller wrote:
The only "phase" remaining is the cos (kz) term, which is really
an amplitude description, not a phase.


Your statement above is in direct contradiction to Gene's statement.

What's so complicated about adding a couple of phasors?


I suspect you know how to add phasors. I suspect you don't have
a clue what that answer means in reality. Please try to convince
us that the 0.707 result above for a 45 degree shift is sheer
coincidence.
