摘要

给出了一种描述各向异性导电层通过平面屏蔽层耦合的波矩阵公式。这种方法包括了屏蔽层内的所有多重反射。得到的波阵可用于计算屏蔽体的屏蔽效能。结果表明,在特定情况下,各向异性多层屏蔽层的屏蔽效能可以用各向同性屏蔽层的屏蔽效能近似表示。此外,对一个有限结构进行了仿真,结果表明,该方法可以正确地预测从各向同性到各向异性屏蔽效能的频率变化。

An extension of Schelkunoff's shielding theory to anisotropic conducting multilayer materials
A wave matrix formulation that describes the coupling through a planar shield of several anisotropic conducting layers is presented in detail. The approach includes all multiple reflections inside the different layers of the shield. The resulting wave matrix can be used to calculate the shielding effectiveness of the shield. As a result it is demonstrated that for specific cases the shielding effectiveness of an anisotropic multilayered shield can be approximated by the shielding effectiveness of an isotropic shield. In addition a finite structure is simulated and it is shown that the method for the infinite structure allows to correctly predict the transition from isotropic to anisotropic shielding effectiveness with respect to frequency.
