Default Where Does the Power Go?

the big confusion factor is using power and energy at all. they are both
derived from the much simpler to handle and understand voltage or current
waves. the biggest problem is that once you change from voltage or current
to power you lose the information necessary to calculate superposition
because you no longer have the phase information from the basic wave
components. this is partly a result of the common use of the swr meter that
measures forward and reflected 'power', everyone thinks they understand how
it works, but very few really do.

The problem with your paper, Cecil, is the part where you try to invent
the "4th Mechanism of Reflection".
