Default Where does it go? (mismatched power)

Roy, unfortunately for your argument, the impedance seen by the
transmitter is:

Z = (Vfor + Vref) / (Ifor + Iref)

where the math is phasor math. ANY DEVIATION AWAY FROM THE Z0-MATCHED
LINE VALUE OF IMPEDANCE = Vfor/Ifor IS *CAUSED* BY THE REFLECTED WAVE!
Given that fact of physics, how can you possibly argue that the
reflected wave doesn't affect dissipation/damage at the transmitter???
