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。
In this paper, the boundary conditions of electromagnetic field are used to derive the transmission field expression of the plane electromagnetic wave perpendicularly incident on the multi-plate flat wave media. Then the impedance theory in transmission line theory is used to solve the problem of reflection of multi-layer slab wave media. Finally, a special case of multi-layer spin wave media slab-double structure type traveling wave absorbing material is analyzed by computer aided design. The analysis shows that double layer instead of single layer can improve the absorbing characteristics of the coating to a certain extent.
