摘要
本文导出了横电磁波传输室(TEM Cell)电场的纵向不均匀性表达式。数值结果与M.L.Crawford(1977)的实验值吻合较好。该结果可用于校正测量探头位置偏差带来的测量误差,从而提高用TEM Cell进行电磁兼容性试验和天线探头校准的测量精度。
By utilizing transmission line theory, practical expressions for the longitudinal non-uniformity of the electric field distribution in TEM cells are obtained. Numerical results agree well with experimental ones shown by M. L. Crawford (1977) at some frequencies. The re-sults presented can be applied in correcting errors caused by probe location deviation in the logitudinal direction so as to reach higher accuracies in EMC measurements and probe cali-bration with TEM cells.
