Well, shucks, that makes it easy.


Just being logical. There are only two directions in a transmission
line, forward and reverse. If all the waves are coherent, all forward
waves superpose to one wave and all reverse waves superpose to one
other wave. Your net forward power is greater than your net reflected
power by the net amount of power accepted by the load. This happens
locally at the load no matter what is happening elsewhere in the
transmission line.

Seems to me, all the terms with a '+' sign would be forward power, by
definition, and all the terms with a '-' sign would be reflected power,
by definition. I don't see any violation of the conservation of energy
principle. The power equation balances.
