摘　　要：本文在高功率微波波形特性分析的基础上,利用模式匹配法和FDTD法对机箱上的各种典型开口、孔、缝隙在高功率微波照射条件下的辐射特性进行了分析,由此评估机箱的屏蔽效能.以此为基础,文中对可能影响机箱屏蔽效能的不同因素如开口方式、吸波材料、来波方向等进行了对比分析,得到了能用于指导机箱结构设计的结论.The radiation performance of typic window、hole and gap under the radiation of high power microwave(HPM) is analyzed by using mode matching method mixed with FDTD method,on the basis of frequency analysis of HPM. The shielding efficiency of the enclosure thus can be evaluated. Some factors affecting the shielding efficiency are analyzed,such as window s type、wave absorbing material and the direction of the incidence. Some useful conclusions are given to guide the design of communication equipment.
