摘　　要：运用电磁仿真软件FEKO进行仿真建模,对混响室条件下小尺寸开缝屏蔽腔体内部的场分布进行了仿真计算,给出了屏蔽体的屏蔽能力与混响室内电磁场的频率、入射方向和极化方向的依赖关系,并利用屏蔽效能的统计定义,讨论了屏蔽效能的特点和规律。As a fundamental research, the electromagnetism simulation software FEKO was applied to simulate the electromagnetic field distribution within a rectangular enclosure with an aperture in the reverberation chamber. The dependence of shielding effectiveheSS （SE）on frequency, the incidence direction, and polarization of applied plane wave were all obtained. By using the statistical definition of SE, the features of shielding effectiveness were analyzed and discussed.
