The solution I gave involved both lumped circuit theory (to calculate the net power) and transmission line theory (to calculate forward and reflected power in a 50 Ohms environment). Lumped circuit theory presupposes that waves do not exist and that RF energy travels instantaneously, faster than the speed of light. You seem to be ignoring the numerous laws of physics violated by the lumped circuit theory. You also seem to be ignoring the fact that when lumped circuit theory yields different results than the distributed network theory, distributed network theory always wins because it is closer to Maxwell's equations. I gave an earlier CLC Pi-Network Tuner example that proved the lumped circuit model fails when reflections are present. EZNEC results are nothing alike when using the lumped inductance option vs the helical wire option for an inductance in a standing wave antenna. If you want this question answered, please open a new thread as it is not relevant to the original question. Asserting that it is not relevant for the purpose of diversion will not make it go away. If one cannot understand, explain, and solve the simplest passive interference problem, how is one ever going to understand, explain, and solve the multiple levels of interference possible within an active source being invaded by reflected energy? If one cannot add one plus one, one is not likely to be able to add two plus two and something akin to that is what I am seeing here. Until one understands exactly how a Z0-match reverses the direction and momentum of a reflected wave, one will not understand what is happening inside a source with incident reflected energy. What is actually happening in reality is revealed when one sticks with the distributed network/wave reflection theory throughout the analysis. People who whine that such is too difficult have to be satisfied with a certain level of ignorance and inaccuracy. -- 73, Cecil, w5dxp.com "Halitosis is better than no breath at all.", Don, KE6AJH/SK |
