中文摘要利用网格粒子云(PIC)模型,在一定条件下,对电离层加热实验中静电波的激发和参量不稳定性的产生,作一维静电粒子模拟.模拟结果表明,SEE的特征与加热泵波频率ω0和电子回旋频率nwce之间的比值有关,入射泵波的电场与地磁场之间的夹角也是影响SEE的一个因素.
英文摘要In this paper a particle-in-cell model is used to simulate the SEE (stimulated electromagnetic emission) produced by the parametric decay instability when a pow-erful high-frequency electromagnetic pump O-wave is launched into F-region of the ionosphere. The simulation results show the ratio of the pump wave frequency(Wce) to the electron cyclotron harmonic frequency (wce) strongly influences the SEE when pump wave frequency is very close to the electron cyclotron frequency. Moreover the angle between the incident pump wave electric field and the geomagnetic field is also a considerable factor to the SEE. For example, for wo=4.2w}e, the SEE is obvious, when the pump electric field is perpendicular to the geomagnetic field, but if the pump electric field is parallel to the geomagnetic field, there is no SEE phenomenon.
