项目摘要
The PI will contribute to quantitative understanding of ionospheric stimulated electromagnetic emission (SEE) through theoretical and numerical simulation models. SEE is a powerful diagnostic tool for nonlinear processes produced during ionospheric modification experiments, and may also be used for general nonlinear processes in plasmas. This investigation utilizes magnetized, kinetic numerical models not used in past investigations, but essential for further progress in studying SEE. Specifically, the PI will: (1) provide a more comprehensive study of three-wave parametric decay processes proposed to produce downshifted sidebands in the SEE spectrum; (2) study four-wave decay processes proposed to produce prominent upshifted sideband features in the SEE spectrum; and (3) study the broadband continuum feature in the SEE spectrum, proposed to result from strongly turbulent interactions in the background plasmas.
PI将有助于通过理论和数值模拟模型定量了解电离层受激电磁发射(SEE)。 SEE是诊断电离层修正实验中产生的非线性过程的有力工具,也可用于诊断等离子体中的一般非线性过程。 这项调查利用磁化,动力学的数值模型没有在过去的调查中使用,但在研究SEE的进一步进展必不可少。 具体而言,PI将:(1)提供对三波参数衰减过程的更全面的研究,提出在SEE谱中产生下移边带;(2)研究四波衰减过程,提出在SEE谱中产生突出的上移边带特征;(3)研究SEE谱中的宽带连续特征,提出由背景等离子体中的强湍流相互作用引起。
