摘要
本文基于电磁场方法,详细导出多层平板屏蔽体对垂直入射均匀平面波的屏蔽效能计算公式。此外,提出计算屏蔽效能时,集肤深度和屏蔽体厚度的约束关系。给出用作计算机机箱的几种常用材料的屏蔽效能计算实例。
The
formulae for the shielding effectiveness of multi layer planar shields against normally incident
uniform plane waves are derived from the electromagnetic field method in detail.In addition,the
limiting conditions between the skin depth and the shield thickness is also presented,and then
shielding effectiveness for a variety of materials commonly used for computer cabinets is
given.
