摘要

The possibility of 3D electron Bernstein wave trapping in intensive magnetic field aligned density fluctuation or blobs in toroidal plasma is demonstrated. A semi-analytic approach for the description of associated plasma cavity is developed. A mechanism of low-threshold parametric decay instability driven by extraordinary pump microwave and leading to the excitation of localized second harmonic electron Bernstein waves and low-frequency heavily damped oscillations is proposed and analysed.
