You're making it sound as though the energy gets to the load by some means other than waves. No, I'm not. The energy in the canceled waves reverses direction and joins the forward wave. That's what I said over on sci.physics.electromag and those guys are amazed that anyone would disagree with that assertion. In other words, the disappearance of two waves during a wave cancellation event can result in reflected energy coherent with those two canceled waves. I don't find that in the literature anywhere. Do you know of a reference? The reply was: I'm curious as to what kind of objections people had. It all makes perfect sense to me. So the disappearance of two waves during a wave cancellation event and a subsequent energy reflection makes perfect sense to real physicists. Not one person on that newsgroup objected to my assertion. There is no flow of energy from source to load via those waves, ... Of course there is. All energy comes from the source. Therefore, the energy in the reflected power Poynting vector originates from the source and is reflected by the load. ERGO, that energy has flowed from the source to the load. *ALL* energy incident upon the load comes from the source, even the energy rejected by the load as reflected energy. The above statement is simply a steady-state shortcut mantra that bears no resemblance to reality. That's your story, and you're sticking with it. I know. ;-) You have not refuted it. Until you provide an iota of proof to the contrary, I'll be sticking with it. Incidentally, your mantras are not proof. Try uttering your mantras on sci.physics.electromag and see what happens. Like we haven't been through this already? The superpostion of V1 and V2 accounts for all the energy that moves from source to load. We've been through all this before. There is not enough energy in |V1|^2/Z02 and |V2|^2/Z02 to support the constructive interference between those two waves. Therefore, an equal magnitude of destructive interference must be occurring somewhere else - according to Hecht. Therefore, the destructive interference energy is generated by the wave cancellation event between the two rearward-traveling reflected waves just as described on the Melles-Griot web page and agreed to by experts over on sci.physics.electromag. How about you reply to my latest posting on sci.physics.electromag so we can obtain opinions from some real experts? I predict our differences would be settled in a matter of days on that newsgroup. -- 73, Cecil, W5DXP |
