Forgot to mention. The Tesla lecture and patent that you show do not depict the importance of the geometry as a complex transmission line. My initial post was to show how to create an optimal meeting of One frequency from two special geometries at a point outside the arrangement. This is what as known in the near field as the evanescent field. Many articles and publications speak of this zone with respect to optics, but this is another name for the same beast. The gap arrangement, and other aspects are important, but the heart of it is how the energy within the structure is shaped, bifurcated, transmitted, reflected by terminal impedance etc. This mode of excitement however will not create single frequencies within the structure. If you pull that off you are very very good at filtering, and have attenuated the energy to a very large degree as well.
