N个横向电磁波的action作用下经典等离子体中横向和纵向电流的产生
The occurrence of transverse and longitudinal electric currents in the classical plasma under the action of N transverse electromagnetic waves
摘要：
考虑了电子气体任意简并度的经典等离子体。在等离子体中传播N（N>2）个共线电磁波。这就需要找到等离子体对这些波的响应。得到了Vlasov方程中两个小参数量的平方律近似分布函数。推导了电流计算公式。结果表明，非线性因素导致了沿波矢方向的纵向电流的产生。该纵向电流与在线性分析中接收的已知横向电流正交。波数的小值的情况下被认为是。
英文摘要：
Classical plasma with arbitrary degree of degeneration of electronic gas is considered. In plasma N (N>2) collinear electromagnatic waves are propagated. It is required to find the response of plasma to these waves. Distribution function in square-law approximation on quantities of two small parameters from Vlasov equation is received. The formula for electric current calculation is deduced. It is demonstrated that the nonlinearity account leads to occurrence of the longitudinal electric current directed along a wave vector. This longitudinal current is orthogonal to the known transversal current received at the linear analysis. The case of small values of wave number is considered.
