多层旋波媒质平板的反射与透射

Reflection and Transmission of Planar Multi-layer Chiral Medium

本文先利用电磁场的边界条件导出平面电磁波垂直入射于多层平板旋波媒质的透射场表达式。然后用传输线理论中的阻抗法，解决了多层平板旋波媒质的反射问题。最后对多层旋波媒质平板的一特例－双层结构型旅波吸波材料进行了计算机辅助设计分析，分析表明，双层代替单层可以在一定程度上改善涂层的吸波特性。

The expression for transmitted wave of planar electromagnetic wave through planarmulti-layer chiral medium is deduced by boundary conditions of electromagnetic field. The reflectance problem is solved by impedance method of transmission line theory, and some ana1yses ofcomputer aided design for two-layer chiral absorption material is presented. Accorrding to theseanalyses,we think that the absorption characteristic of the chiral coated-layer can be improved to acertain degree if single-layer is replaced with two-layer.
