For the purpose of driving a secondary or set of secondaries at harmonic
frequencies one could consider a pulse forming network(PFN). A PFN is built
basically like this.  More Ls and Cs can be added as desired.


------L------------L-------- output
   |         |         |
   C         C         C
   |         |         |

A PFN can be used to deliver an approximately square pulse into a resistive
load.  There would obviously be some mismatch effects into the primary of a
Tesla coil.  With a minimum number of Ls and Cs, the values could be chosen
to favor the desired harmonics.

Has anyone experimented with this?
