2. As for the wave cancellation part, you have many times noted that
stuff happens at interfaces or discontinuities. So why is it that you
never ever consider what is happening inside those interfaces and
discontinuities? Do you suppose the waves simply cancel, reflect, or
whatever without assistance from the materials in the interface or
discontinuity? Do you suppose that any energy or momentum considerations
may need to include the materials?

That's one of the points I have been trying to make. The impedance
discontinuities perform the same function as half-silvered mirrors,
for instance, in interferometers. The impedance discontinuity is a
primitive interferometer.

On the other
hand there is no possibility of figuring out how the waves actually
"cancel" or what happens to the energy and momentum without considering
the actual physical configuration.

The point is that optical physicists already had it figured
out before any of us were born. The problem is that RF gurus
tend to reject any technical facts from the field of optics.

You, for instance, called me every name in the book while
arguing loud and long against any of those concepts from
the field of optical physics. Now you admit that some of
them are valid but completely unimportant. That is, at least,
an improvement.
