I really do wish you'd learn to read. I did NOT say I don't care
where the power goes.


I care where the power goes, too. And I know where it goes: from my
transmitter through the transmission line to the antenna.

Roy, here's a quote from your web page:
"I personally don't have a compulsion to understand
where this power 'goes'."

How can you care where the power goes when you don't care
to understand where the power goes?

You also scream out:
"THE REVERSE POWER IS NOT DISSIPATED IN OR ABSORBED BY THE
SOURCE RESISTANCE."

I just presented a special case example where all of the
reverse energy is dissipated (converted to heat) in the
source resistance. All it takes is one example to prove
your above statement to be false.

Your web page even contains one of those special case
examples. When your load is 0 +/- j50 at the end of
a 1/2WL piece of 50 ohm line, the forward wave and
reflected wave are 90 degrees out of phase at the
50 ohm source resistor. Under that special condition,
all of the reflected energy is dissipated in the
source resistor. Your own example proves your statement
to be false.
