The Procedure Of Examination Of The Stability Of Boundary Between Plasma And The Magnetic Field In Electroneutral Approach

V. V. Lyahov, V. M. Neshchadim

摘要:

发展了一种研究等离子体与磁场边界层不稳定性的方法。由于某种原因,层间平衡并不成立,而是由具有自洽电磁场的动力学方程的严格解得出的。Nicolson溶液用作平衡溶液。在此基础上,计算了模拟介质层(边界层)的介电磁导率张量。这个张量本质上不同于已知的磁致等离子体张量。从麦克斯韦方程组出发,推导出了电场扰动方程。提出了一种确定边界层扰动频散特性的方法。该理论适用于热非相对论等离子体。

英文摘要:

A procedure that allows study of unstable stability of a boundary layer between plasma and a magnetic field has been developed. Layer equilibrium for one reason or another is not set but follows from strict solution of kinetic equation with self-consistent electromagnetic field. Nicolson's solution was used as equilibrium solution. The non-equilibrium component to the distribution function was found and on this basis tensor of dielectric permeability simulating the medium was (boundary layer) is calculated. This tensor essentially differs from the known tensor for magnetoactive plasma. Equations for electric field perturbation were obtained from the Maxwell's equations completed with the derived constitutive equation. The technique of determination of dispersion characteristics of perturbations of a boundary layer was proposed. The theory is applicable to thermal nonrelativistic plasma.
