Resistive is good :).

And since this is an electromagnetic wave, they most certainly are.

Look up Alven waves, et. Wish I could find the URL to an online book on the earth's magnetosphere and all of its modes.
Unfortunately, my plasma book is currently in the hands of my partner, and therefore not on hand. However, I do know what you are talking about. The question I am asking is how the presence of the plasma affects the resonance of the electromagnetic waves.
