摘　　要：电磁屏蔽效能取决于屏蔽体薄弱环节,只有屏蔽体的所有组成部分都能达到屏蔽效能要求,才能满足屏蔽体的整体屏蔽要求。在工程实践中,由于功能要求,电子设备的屏蔽体会留有各种各样的孔洞或缝隙,如通风散热孔等,解决这些问题最有效的方法就是截止波导。Electromagnetic shielding effectiveness depends on the weak link of the shield.In order to meet the overall rating of the shield, only the shielding of the various components to achieve shielding effectiveness. In engineering practice, as the functional requirements, the shielding of the electronic devices experience left a variety of holes or gaps, such as ventilation holes, the most effective way to solve these problems is the cutoff waveguide.

关 键 词：电磁屏蔽 截止波导 屏蔽效能
