摘要

电磁屏蔽理论的基础为导电材料提供了良好的结果，反射是产生屏蔽效果的主要现象。本文讨论了导电性能较差(如铁氧体)但具有重要吸收性能的材料(基于宏观参数/spl epsiv/和/spl mu/)的SE/sub dB/(屏蔽效能)的测定。所提出的理论与使用同轴TEM细胞的SE/sub dB/测量方法相匹配。

SE/sub dB/ determination for non-conductive electromagnetic absorbers

The basics of electromagnetic shielding theory provide good results for conductive materials, reflection being the main phenomenon in producing the shielding effect. The paper deals with the determination of SE/sub dB/ (shielding effectiveness) in the case of materials which are less conductive (like ferrites) but with important absorbing properties (based on macroscopic parameters /spl epsiv/ and /spl mu/). The theory presented matches the SE/sub dB/ measuring methods that use coaxial TEM cells.
