This project concerns itself with the electrodynamics of waves and their interactions in magnetized plasmas. The proposed research places emphasis on new approaches and understanding of nonlinear plasma electrodynamics phenomena associated with coherent versus chaotic dynamics. This encompasses three interrelated, major studies: (1) Chaotic dynamics and diffusion; (2) Wave induced chaos and spatial diffusion; and (3) Space-time chaos from instability. The major objective of the theoretical work of this project is the modeling and understanding of the above mentioned phenomena as they relate to new and potentially significant engineering and scientific applications. These include plasma heating, modification of transport, and control of instabilities, as for example in energetic plasmas for coherent electromagnetic sources, in fusion energy research, in ionospheric and space propagation studies, and in fluid dynamic flows. Wherever possible and appropriate, relevant and ongoing experimental work is used to test and evaluate the analytical results. The proposed work seeks to emphasize the advance in our basic understanding of plasma electrodynamics that may transcend current experiments and applications.

该项目涉及波的电动力学及其在磁化等离子体中的相互作用。 拟议的研究重点是对与相干动力学与混沌动力学相关的非线性等离子体电动力学现象的新方法和理解。 这包括三个相互关联的主要研究：（1）混沌动力学和扩散； (2) 波引起的混沌和空间扩散； (3)不稳定造成的时空混乱。 该项目理论工作的主要目标是对上述现象进行建模和理解，因为它们与新的和潜在的重要工程和科学应用有关。 这些包括等离子体加热、输运修改和不稳定性控制，例如用于相干电磁源的高能等离子体、聚变能研究、电离层和空间传播研究以及流体动力学流动。 在可能和适当的情况下，使用相关且正在进行的实验工作来测试和评估分析结果。 拟议的工作旨在强调我们对等离子体电动力学的基本理解的进步，这可能超越当前的实验和应用。
