中文摘要	金属线列横电磁波(WTEM)小室是一种新型电磁兼容试验设备。对WTEM小室的场分布特性进行了数值分析。采用边界元法分析了WTEM小室的准静态场分布,采用有限元法计算了WTEM室的高次模截止频率,并与TEM小室进行了对比,最后采用时域有限差分(FDTD)法分析了WTEM小室的场均匀性和交叉极化特性。计算结果表明:金属线列的内导体有助于减弱水平方向的高次模;通过金属线列的优化排列可显著扩展可用测试区;场均匀性满足6 dB准则,不过,高于一定频带后交叉极化特性下降,但仍满足放松要求。WTEM小室用于宽频带电磁兼容试验可行。; The wire transverse electromagnetic(WTEM) cell is a new equipment for electromagnetic compatibility(EMC) test.The quasi-static field distribution inside WTEM cell is analyzed by boundary-element method,then the higher order mode cutoff frequencies were calculated using finite-element method,and compared with that of transverse electromagnetic(TEM) cell,The field uniformity and cross-polarization performance of WTEM cell are analyzed by three-dimensional finite-difference time-domain(FDTD) method.The numerical results show that the wire array inner conductor can mitigate the horizontal higher-order mode,and the available test volume in which the field uniformity of WTEM cell satisfy the 6 dB criteria can be enlarged through optimizing the arrangement of wire array.Although the cross-polarization performance will degrade over a certain frequency band,it still fulfills the relaxed requirement.The WTEM cell can be used for wide frequency band EMC test.; 【作者单位】南京航空航天大学机电学院；东南大学电磁兼容研究室江苏南京210016集美大学机械工程学院；福建厦门361021；江苏南京210016；江苏南京210096；【作者英文名】HU Yu-sheng1,3 ZHU Jian-ying1 JIANG Quan-xing2(1.College of Mechanical and Electrical Engineering,Nanjing University of Aeronautics and Astronautics,Nanjing Jiangsu 210016,China;2.Electromagnetic Compatibility Laboratory,Southeast University,Nanjing
