PI将有助于通过理论和数值模拟模型对电离层受激电磁发射(SEE)进行定量理解。对于电离层修正实验中产生的非线性过程,SEE是一种强大的诊断工具,也可以用于等离子体中一般的非线性过程。这项研究利用了过去研究中没有使用的磁化动力学数值模型,但对于进一步研究SEE是必不可少的。具体地说,PI将:(1)更全面地研究在SEE光谱中产生下移边带的三波参数衰减过程;(2)研究在SEE光谱中产生显著上移边带特征的四波衰减过程;以及(3)研究SEE光谱中的宽带连续谱特征,该特征被认为是背景等离子体中强烈湍流相互作用的结果。
英文摘要
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.
