| 摘 要： | 本文简要地回顾了“磁窗”减轻再入通讯中断的机理。推导出线极化波,园极化波穿透磁等离子体薄层时,场量的传输矩阵。给出了功率反射系数及透射系数表达式。通过这种磁窗理论模型,模拟算出了为减轻或消除再入通讯中断所需要的磁场强度。并通过激波管上进行的磁窗模拟试验,证实了这一结论。

| Abstract: | In this paper, the mechanism for eliminating re-entry black-out by meansof magnetic window is briefly reviewed. A theoretical model of circularly polarized EMwave through magneto-plasma slab is derived. Numerical simulations are conducted todetermine the effects of magnetic field on the re-entry black-out and compared with theexperimental results which are obtained in a shock wave tube. |
