I tried using the existing objects to accomplish this but I was never
satisfied with the results. For example, half a streamer on both sides
of a toroid is "not' linear to a single streamer on one side. Once I
realized this, I knew I needed Paul Nicholson. I wrote an email to
Paul for the implementation of this into Geotc, but at the time he
wasn't getting my emails (lost in cyberspace I think). Paul also hates
JavaScript more than I do (no, I don't think so!), so likely this
can't be done unless I can figure a method to use existing objects. I
have only at my disposal toroids, spheres, cylinders, and discs. All
of these I can configure into a "rod" shape, however, they all
implement out on both sides from the center of the coil and that is my
problem. I couldn't find my happy spot and eventually got busy with
other things never to resolve this situation. I still long to do it.
The only element that can be configured as a rod is a vertical thin
cylinder. What looks as rods to both sides is actually a disk. A true 3D
simulator can be written, but it would take much longer to do the
calculations.
I would never try to tune a coil by adjusting separately the resonance
frequencies of both coils. What I do is to apply a low-impedance (<1
Ohm) low-frequency (1 kHz) square wave across the spark gap and observe
the transients across the primary coil in an oscilloscope at the
transitions. I then adjust the system to obtain complete notches, what
indicates that complete energy transfer is occurring. This method gives
complete information about what is happening with the whole system.
