I'm afraid you are too late with that advice. Optical physicists have
assigned reality to forward and reflected waves inside an
interferometer and have tracked all of the energy including the energy
in canceled wavefronts.

Scroll down to, "Using Dielectric Beamsplitters to find the "missing
energy" in destructive interference" It says: "... when interference
is destructive at the standard output, it is constructive at the non-
standard output."

In RF terms, when interference is destructive at a Z0-match, it is
constructive in the direction of the load.

You have fallen in to the same trap that you did with circulators.
When you introduce a circulator in to the transmission line, you
change the experiment and you get certain results. The circulator
provides some numerology that appears to support the hypothesis
of 'reflected energy' being real. The same with looking for
"missing energy" (note they even quote it) with a beamsplitter.
The beamsplitter reveals what is happening at the beamsplitter,
not what is happening at points between the two beamsplitters.

Just like a circulator.

he is even more hopeless than most, first he determines there are
forward and reflected waves when a dc source has charged the line,
then he rejects circulators and beamsplitters that obviously work
because of the waves. so dc waves exist, but rf and optical waves
don't. thats a unique viewpoint.
