Effects of Magnetic Shear on Lower Hybrid Waves in the Suprauroral Region.

Abstract

Effects of magnetic shear on lower hybrid modes are investigated. It is shown that due to non-local effects, even a small shear can significantly affect the instability, leading to stabilization for some parameter ranges. These results are of importance in the context of the recently proposed mechanism of lower hybrid acceleration and ion evolution in the suprauroral region. Originator supplied keywords: Lower hybrid waves, Magnetic shear, Ion acceleration, Suprauroral plasma waves, Conics, Plasma instabilities.
