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. -- 73, Cecil http://www.w5dxp.com |
