Some topics:
Arc and Spark resistance - typical curves
Spark Gap Transmitters
Tuned coupled circuits ala  tesla type circuits
	also some oscillograms of real circuits beating
Nice collection of Inductance formulas for
	various coil geometries

Industrial High frequency Electric Power - E. May

Arc and tube-type power oscillators for induction heating, etc..

-Ed Harris
