and there is a book on signal propagation black magic

I have this fantastic book. It is mostly about measurement and keeping the loop areas as small as possible so the high frequencies are still visable.
The emphasis with DPF is I think slightly different in that we are trying to get as much energy into the plasma as we can before it detaches from the electrodes and forms the plasmoid.
Maybe we should be thinking about what can be done to delay the plasmoid formation so that the energy transfer can be maximised?
(edit) Actually, a lot of the book is about good termination too
