基于FEKO评估孔缝对金属腔屏蔽效能的影响
Assessment of the Impact on Shielding Effectiveness by the Slot on
Metal Cavity Based on FEKO
摘要 采用FEKO电磁仿真软件,从模型建立、入射波设置到求解结果设置,逐步介绍了金属腔屏蔽效能的分析方法,并探讨了缝隙长度、形状和穿透对屏蔽效能的影响。结果表明:电磁泄漏的关键是缝隙的最大尺寸而非总面积;穿透是屏蔽效能的“杀手”。最后,给出了改善屏蔽效能的建议。
关键词 屏蔽效能;缝隙;穿透;FEKO
Abstract The electromagnetic simulation software FEKO is adopted. The analytical process
of metal cavity shielding property is introduced through step such as,model setup,incident
wave and solving results setting. And also the effects of aperture length, shape and
penetration on shielding effectiveness are discussed. The results show that maximum
length of aperture is the key factor of electromagnetic leakage, rather than the total area.
Penetration is the "killer" of shielding property. In the end, the advice is given to improve
shielding property.
Keywords shielding effectiveness; aperture; penetration; FEKO
