And the laws of scientific logic, for example: sticking to your initial

OK, let's take an example. The source (SGCL) is a signal generator with
a circulator and 50 ohm resistor circulator load. The load is a 291.5
ohm resistor.
100W SGCL---Bird---50 ohm lossless coax---291.5 ohm load
We measure 50 watts delivered to the 291.5 ohm load. We measure 50
watts dissipated in the 50 ohm circulator load resistor. The Bird reads
100 watts forward power and 50 watts reflected power. Modulation proves
that the 50 watts absorbed in the circulator resistor has made a round
trip to the 291.5 ohm load and back. Everything obeys the laws of
physics embodied in the wave reflection model and the conservation of
energy/momentum principles. What else is there to know?
