摘要
利用电磁场方法分析了正入射平面波的屏蔽问题,讨论了电磁场方法与传输线方法的等效性,并用传输线模拟方法提出了任意多层平板屏蔽体对正入射平面波的屏蔽系数计算公式,纠正了以往计算中的一些错误.
In the paper,shielding problem for plane shields is analysed first by EM method.The equivalence of EM method to transmission line model is dis- cussed,and an approach to calculate shielding effectiveness for multi-layer plane shield is presented by means of transmission line method,in which,some pre- vious errors are corrected.
