I don`t remember chapter and verse anymore. So, I can`t say where Terman
first writes of power in these waves. On page 88 of Terman`s 1955
edition he says:
"At radio frequencies it is nearly always permissible to assume that
omega L R, and omega C G. To the extent that it is true, one can
rewrite Eqs. (4-5) and (4-7) as follows:
Zo = sq rt L/C

This means current is in-phase with voltage in the waves in both
directions.

In-phase volts and amps are real power, not apparent power.

Maybe. Sort of. Not necessarily.

I agree completely when the volts and amps are the measurable
resultant volts and amps.

But when the volts and amps are contributary terms to a
superposition solution, then, in general (using my definition
of general), multiplying them to produce watts is an
invalid operation since the watts terms can not be superposed
to obtain resultant watts.

It is, I suspect, for this reason that Johnson is fuzzy about
the power in forward and reverse waves; superposition, does
not, in general, apply for power.

The question is, was Terman similarly circumspect?
