Default Where Does the Power Go?

Jim, the reflected energy and momentum changes direction.
Walter Maxwell calls it a virtual short or open with a
virtual reflection coefficient of 1.0. I agree with "Optics",
by Hecht, that it is total destructive interference in the
source direction accompanied by total constructive interference
in the load direction. What do you call it? What reflection
coefficient does your reflected wave see? Please give it a
name.


I agree with Optics by Hecht too, Cecil. I just don't always agree with
what you think the words in Optics by Hecht mean.


That the reflected wave(s) have reversed momentum is a fact
since at one point they are measured as photonic energy
traveling toward the source and at another point they are
measured as having disappeared. Remember, these are photonic
EM waves. They necessarily must travel at the speed of light
or not exist. The photonic component waves in non-reflective
glass all travel at the speed of light. In like manner, so
do the photonic component RF waves in a transmission line.
Photonic EM waves don't change their basic nature with frequency.

You still didn't give me a word for that change in momentum.
Walter Maxwell calls it "re-reflected". I would be satisfied
with "re-directed' or "momentum-reversed". What would you
like to name it?

While you are at it, you never did give me a word for watts
that are not power.
