Can someone tell me how to calculate the _proportion_ (not numerical
quantity) of EM energy residing in a fundamental frequency as opposed
to a distant lower harmonic of same?

For example, an RF fundamental and the frequency obtained by dividing
it in successively in two 20 or 30 times.

Thank you,

Jim Slatter

Wouldn't that depend on the shape of the waveform?

Indeed it does. Pure sine waves, for example, have no harmonics. A
distorted sine wave has harmonics proportional to the percentage of
distortion.
