Plasma Instabilities in the High and Low Latitude E-Region Induced by High Power Radio Waves

Abstract

The effect of a high frequency (HF) powerful pump wave on high and low latitude E-region low frequency plasma instabilities is theoretically considered. The growth rates and threshold criteria are calculated for the electrojet associated (Farley-Buneman, gradient-drift) and higher altitude high latitude parallel-current associated (ion-acoustic, ion cyclotron, current convective) instabilities. The results are discussed in the context of present ionospheric modification (heating) experiments, for the high and low latitude ionosphere. Keywords: Ionospheric heating, Plasma instabilities, E-region, High latitude.
