摘　　要：横电磁波传输室广泛应用于电磁兼容试验中,当置入受试设备后,其中的场分布会发生扰动。本文采用边界元法分析了横电磁波传输室中置入金属箱体的受试设备后场分布的规律,对受试设备所受暴露场的场强进行了计算,并提出了具体的估算方法。对空载时横电磁波传输室的场分布进行了测量,测量结果证实了计算方法的正确性。TEM (Transverse Electromagnetic)cell is widely used in electromagnetic compatibility (EMC) test. When Loaded with equipment under test(EUT) , the electric field in TEM cell will be distorted. In this paper, the field distribution in TEM cell loaded with metallic EUT is analyzed by boundary-element method (BEM), and the electric field strength exposed to the EUT is calculated. The measured results agree very well with the calculated one. The obtained results are useful for sensitivity test.
