概要

• 論文の詳細を見る

• We study the mechanism of stimulated electromagnetic emissions, called Broad Upshifted Maximum (BUM) feature observed in high-frequency ionospheric heating experiments with the aid of two-dimensional electromagnetic particle computer experiments. The pump is set up as an O-mode wave in the computer experiments propagating through the plasma with small-scale field aligned irregularity. A proposed theoretical study shows that the irregularity is important in the excitation mechanism. High-frequency electromagnetic emissions are observed, accompanied by electrostatic upper hybrid and lower hybrid waves in agreement with the theory.
