摘要

基于传输线和波导理论, 提出了一种用于计算覆盖中等导电性材料的金属腔体电磁屏蔽效能的解析理论模型, 并通过和全波电磁模拟结果的比较检验了该模型的有效性. 计算分析了屏蔽体屏蔽效能的位置效应和谐振效应. 建议了一种评价导电材料电磁屏蔽效能的方法, 能很好的削弱谐振效应和位置效应的影响, 直接反映出材料本身的电磁屏蔽效能.

关键词:

The electromagnetic shielding effectiveness (SE) of a metal cavity covered by a material of medium conductivity is investigated theoretically by using an equivalent circuit method based on the transmission line and waveguide theory. The validity of the theoretical model is verified by comparison with the electromagnetic simulation software. The position effect and the resonance effect of the SE are calculated. A method for evaluating the SE of materials is suggested. With this method, the influence of the resonance effect and the position effect can be impaired greatly, also the SE of materials against plane wave can be evaluated directly.
