Randall, forgive me for assuming, but your reference to this last post by Mr. Dollard as "a" or "the" presentation gives me the impression that you are not aware of the rest of it. I, unfortunately, cannot answer your questions myself, and my experience with math only goes one imaginary layer deep, so I would just ask you whether you have read though the compilation here
, and the references cited as "necessary."
Hopefully, we can all help each other to understand this work. I'm still waiting to see who gets the gold star for the Magnetic/Dielectric field ratio question.
