This project will investigate the phenomenon of broadband electrostatic noise (BEN) that has been observed in the Earth's magnetotail. The project will examine a recent model for the production of BEN which involves both trapped solitary waves and an untrapped, large region of non-solitary waves. It will focus on developing two aspects of the model: (1) the non-linear theory of trapped solitary waves in a general magnetized plasma, and (2) the evolution of non-solitary waves associated with beam-plasma instabilities in inhomogeneous plasmas.

该项目将调查在地球磁尾观测到的宽带静电噪声现象。 该项目将检查最近的模型，为生产的BEN，其中包括被困孤立波和一个未被困，大面积的非孤立波。 它将集中于发展该模型的两个方面：（1）一般磁化等离子体中俘获孤波的非线性理论，和（2）非均匀等离子体中与束-等离子体不稳定性相关的非孤波的演化。
