MLD结构下电磁兼容混响室内场均匀性分析

Analysis of Field Homogeneity in Electromagnetic Compatibility Reverberation Cabinet under MLD Configuration

为了进一步提高电磁兼容混响室内场均匀性,提出了最大长度散射体(MLD)一种新的位置,通过时域有限差分(FDTD)方法对混响室内的场进行了仿真分析,并与设置搅拌器情况下的混响室内场均匀性以及散射体位于混响室内6个面情况下混响室内的场均匀性作了比较。结果表明提出的散射体位置可有效地提高混响室内场均匀性。

For raising the field homogeneity in electromagnetic compatibility reverberation cabinet further,this paper presents a kind of new position of maximum length diffuser（MLD）,performs the simulation analysis to the field in reverberation cabinet through finite-difference time-domain（FDTD） method,and compares it with the field homogeneity in reverberation cabinet under the state of setting beater and the field homogeneity in reverberation cabinet under the state that the scatter is on the 6 surfaces in reverberation cabinet,the result shows that the position of scatter presented in this paper can raise the field homogeneity in reverberation cabinet effectively.
