I must have missed the posting where you proved RF waves do not obey
the *average* power density (irradiance) equation from "Optics", by
Hecht. Neither Hecht nor I have ever said anything about instantaneous
virtual power except that it is "of limited usefulness". Nothing you
have posted about instantaneous virtual power has disagreed or
disproved anything that I have said about *average* power where I
simply quoted Hecht.

Ahhh, so you are only claiming that 'on average', the energy does not
enter the PA or 'on average' the energy is reflected.

The finer grained time domain analysis, reveals that some energy does
enter the PA, but that it comes back out again to keep the average the
same.

So if you want to live with the coarser, less complete models, that
is
fine as long as you understand the limitations of your model. It would
be good if you were to articulate these limitations to the readers
to reduce confusion.

Of course, if you are happy with averages, it is not obvious to me
why you want to bother with separating the signal in to forward
and reflected. Why not just use the overall average energy flowing
towards the load.
