| 摘 要： | 为了在混响室的设计过程中合理地选择材料,以达到优化混响室场性能的目的,采用基于矩量法的电磁仿真软件FEKO分别对使用3种不同磁导率材料混响室的电磁场进行了仿真计算,从场强大小和场均匀性两个方面研究了材料磁导率对混响室场性能的影响。仿真结果表明:材料的磁导率越大,混响室内电场强度的各分量最大值和场强平均值越小,并且材料磁导率的变化不改变混响室内电场的分布情况。从场均匀性方面来看,对于3种不同磁导率材料的混响室,在80和150MHz频点处,其场均匀性均满足标准IEC61000-4-21的要求。

| Abstract: | In order to appropriately choose material during reverberation chamber design and to optimize performance of the electromagnetic field,electromagnetic simulation software FEKO based on MOM was used to calculate the electromagnetic field of the three reverberation chambers with material of different permeability. Effects of three materials with different permeability on field performance of reverberation chamber including field strength and field uniformity were studied by computer simulation technology.
