A number of problems have been bothering me that may be solved. I couldn't describe why the height of the chamber had to be dictated by the wavelength of the wave, or pinpoint where I read that. I didn't fully understand what a mode was. And, I didn't know whether the lambdag equation would work in a frustum as it did in a waveguide. This came from failing to understand that E is not oriented as in Feynmann II 23-11(a), but 23-11(b). It was very helpful to understand what was happening, but in a waveguide E goes across teh guide to allow the EM wave to propogate down it. (Feynmann II 24-3(a), Balanis Fig. 1, attached figure 1). So, figure 2 is wrong, figure 3 is more correct. This orients the propagation between the endplates, prevents the sloping sides from being near-tangential from E (meaning we are not at a non-zero portion of the Bessel function, preserving the lambeg equation) and changes the way I understand the current flow. It also explains why teh resonance modes in Tajmar were so clear; the sloped sides dampened resonance when the propagation was oriented sideways. Only TE resonance modes were appearing. This changes the way I will orient the antennas, at least. It also changes how I understand the connectivity of the loop antennas. I was so fixated on Feynmann II 23-15 that I missed Feynmann II 23-8, which shows a loop antenna and the obvious implication that the coaxial sheath shoudl be connected to the interior wall.
