IIRC, plasma is resistive and radiates away energy, unless magnetic fields are present (they usualy are) which result in effective capacitance across the field lines, which in turn will effect (decrease the cyclotron) resonant frequency, but also can add many more modes of vibrations (some modes increase frequency with increasing B-field). 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.
