EM waves are EM waves, Keith, no matter what the frequency.
EM waves all obey the laws of reflection physics, superposition,
and conservation of energy principle. If you want to prove those
laws to be invalid and replace them with ones of your own design,
be our guest.

Cecil,

It is likely that all of these interference-related items you like to
quote from Hecht are cast in an environment of lossless optical
components. The characteristic impedance is set by the index of
refraction of the various layers, but none of the optical layers have
any absorption.

Soooo, how does any of this optical stuff extend to making arguments
about the absorption or re-reflection of energy in the source resistor
for the HF case?

The laws of physics may be inviolate, but it is not quite so clear that
your derived and extended models share the same characteristic.
