Well, it's certainly not going to work with the flat plate close spacing
model.

Later, I want to look at the effects that happen if the cylinder isn't
circular, when the hand is very close, as opposed to say 10's of diameters
away. I do think that carving it into pieces might get to a pretty good
approximation ala FEA.

Hi Dave,

Shape will probably have very little to do with it. If anything, the
computation by parts reveals that the last 90% of the rod is more or
less superfluous to the total value (at least for my example).

Time to break out that XXth century museum piece, the Smith Chart.

Hmm.. I just picked up a smith chart implementation in mathcad.

Post me that file, would you?

Look down just a bit.

Trying actual hardware, the last 1/8 inch is very significant, shifting the
oscillator several hundred Hz.
