Are you really prepared to throw away P = VI?


yes, when the V and I are the superimposed voltage and current that
you insist are the real current and voltage on the line.


Amazing! I suppose Ohm's law is next?


Hopefully, you realize that P = VI only works for DC.
AC and RF, with their associated phase angles, are much
more complicated than P = VI. As a matter of fact, if
you use P = VI for standing waves, you are infinitely
wrong. There is no power in standing waves no matter
what the voltage and current magnitudes.
