摘　　要：用两点边值问题的方法,数值求解了任意入射角的平面电磁波在任意极化方向的任意平面分层不均匀等离子体中的反射与透射;通过建立任意分层介质的物理模型,给出了电磁波的统治方程;在假设电场垂直与平行于入射面的2种条件下,运用IMSL的子程序BVPFD计算给出了数值结果.数值结果显示:当归一化频率小于1.3时,大部分反射,小部分透射;而当归一化频率大于1.3时,则小部分反射,大部分透射.The method of two points was used for the calculation of the reflection and transmission of electromagnetic wave with arbitrary incident angle in nonuniform plasma layer of arbitrary direction of magnetization.By constructing the physical model of arbitrary layered media,the governing equations of electromagnetic wave and the boundary conditions were given.On the assumption that the electromagnetic wave neet plumb or parallel the plane of incidence,the sub program of IMSL（International Mathematics and Statistics Library） BCPFD was used to calculate the numerical results.The numerical results show that when the normalized frequency is below 1.3,most of the waves are reflected.And when the normalized frequency is above 1.3,most of the waves are transmitted.
