In this paper, the influence of plasma turbulence due to the sheared and body stress flow on the dispersion characteristics of the transverse electromagnetic modes in strongly coupled plasma is analysed. Using kinetic theory and solving the scattering relationship for the Vlasov-Maxwell system, the influence of plasma turbulence on the growth of the electromagnetic mode is investigated. The minimum value of the stress rate threshold for the growth rate of electromagnetic instability in the linear polarization is higher than that of circular polarization. It is shown that the instability growth rate maximum for the circular polarization is about 100 times higher than that of the linear polarization. In the circular polarization, the value minimum of the shear stress is 1.2 times the minimum volume of the body stress. For the linear polarization, the value minimum of the body stress is 1.5 times the minimum volume of the shear stress. Increasing the density gradient of plasma leads to a higher stress threshold rate, and the range of propagation angles of growing modes is limited. With increasing steps of the density gradient plasma in the low-density corona, electromagnetic instability occurs at a higher stress flow.

等离子体湍流中的各向异性等离子体波

本文分析了强耦合等离子体中剪切应力流和体应力流引起的等离子体湍流对横向电磁模色散特性的影响。利用动力学理论,求解Vlasov-Maxwell系统的散射关系,研究了等离子体湍流对电磁模式生长的影响。线极化中电磁不稳定性增长速率的应力率阈值最小值高于圆极化。结果表明,圆极化的最大不稳定性增长率大约是线极化的 100 倍。在圆极化中,剪切应力的最小值是体应力最小体积的1.2倍。对于线偏振,体应力的最小值是剪应力最小体积的 1.5 倍。增加等离子体的密度梯度导致更高的应力阈值率,并且生长模式的传播角度范围受到限制。随着低密度电晕中密度梯度等离子体步长的增加,电磁不稳定性发生在较高的应力流处。
