Nothing the IEEE says counters the fact that the mathematical product
of two physical quantities does not and can not physically propagate
through a transmission line. It can also not reflect, refract,
diffract, superpose, or interfere constructively or destructively.
Waves propagate and energy moves. Power is simply the rate at which
energy is transferred or changes form. It is the rate at which
'electric smoke' is liberated from one's aerial so to speak.

Steady-state had a beginning and it will have an end. It
cannot be analyzed without knowing what happened in the
beginning and what will happen in the end.

But there's no dispute about what happens in the beginning or at the
end. It's entirely about what you claim is happening in the steady
state.

Steady-state
is the rug under which you and others try to sweep the
laws of physics including the conservation of energy
principle.

The steady-state condition isn't something which contradicts nature -
it IS nature. Clearly, the only one needing to sweep the laws of
physics under the rug around here is you, Cecil.
