| 摘 要： | 本文阐述了传输线模型在电磁屏蔽效能中的应用，发展了平面波屏蔽理论，并对单层及多层媒质的情况进行了讨论。文中给出了带有一般参数的屏蔽效能基本表达式，可方便地用于多层媒质的屏蔽效能计算。它也能用于垂直或斜入射到多层非损耗性各向同性媒质（包括绝缘介质和金属镀层）的多频段设计中。本文利用传输线模型对Ａ类夹层屏蔽结构进行了多频段分析和设计。

| Abstract: | The application of transmissionline modeling (TLM)to electromagnetic shielding effectiveness is described.Plane wave shielding theory is developed and discussed for a number of important cases such as single and multilayered media .For application of design,the basic expressions are given and plotted with universal parameters for convenient use in shielding effectiveness calculations of a multilayered media. It can be applied to multiband design under vertical or oblique incidence to lossless isotropic media of a number of dielectric and for metallic layers. This paper presents the analysis and design of multiband shielding effectiveness for a type, a sandwich using transmissionline modeling. |
