What you seem to be missing, Tom, is that if the two signals
are not coherent, interference is not possible.


There is NO WAY I'm interested in moving to a one-dimensional world
that requires me to special-case a particular type of wave to get the
right answer and FORSAKE the multi-dimensional linear circuits world
I'm in, that quite accurately describes what happens regardless of the
content of forward and reverse.


Coherency, non-coherency, and interference is covered well
in "Optics" by Hecht and other textbooks. Optical physicists
have been tracking the EM energy flow for centuries. This
information may be new to you but it is old hat in physics.

What I have proved in Part 1 is that average reflected energy
is not always reflected back toward the load. Equally false
is the flip side old wives tale that says: "Reflected energy
is always dissipated in the source."

It's takes only one case to prove an old wives' tale to
be false. That's why I chose the special case of zero
interference. One needs to understand the special case of
zero interference before one tries to understand the general
case involving interference which will be Part 2 and Part 3
of my articles.

If you choose to remain ignorant, "NO WAY I'm interested",
then that's your choice and that's OK. But understanding
interference is the easiest way I know of to track the
energy flow.

Your one-dimensional world apparently
limits you to thinking about interference in a way that mine does
not. I may post the results of a 'speriment I'm setting up in a day
or two that may spark some interesting discussion. Till then, I'm
outta here.


If you come up with an easier analysis of average energy flow
and average power, that will be great.
