摘　　要：强电磁脉冲能够在孔缝等处通过耦合进入舱体内部,破坏舰艇内部的电子设备.为保护舰艇内部的电子设备,提出了在舱体通风孔处安装交错排列的多层截止波导式通风窗,来逐渐减弱强电磁脉冲进入舱体的耦合场强.通过应用FDTD法对该防护方案的计算机仿真与分析,表明该方案不仅具有良好的防护效果,并且实用可行.EMP can enter the inside cabin in the slot or hole through coupling to damage the electronic equipment. To protect the electronic equipments, the scheme of installing the multi-layer cut-off wave-guide windows by interlacement at the blowhole of the cabin is proposed to gradually weaken the coupling field intensity of the EMP which enters the cabin. The computer simulation and analysis of the protection scheme by the FDTD method show that it not only has a good protection effect but also is feasible and practical.
