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。
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 effec~ of aperture length, shape and penetration on shidding effectiveness are discussed. The results show that maximum length of aperturo is the key factor of cleric leakage, rather than the total area, Penetration is the ＂killer＂ of shielding property. In the end, the advice is given to improve shielding property.
