摘要
多导体传输线高频场线耦合研究是当前电磁兼容研究的重点和难点,而多导体传输线上的耦合响应与线上的高频分布参数紧密相关。由于经典传输线理论中采用准TEM波近似,使其不适用于求解高频分布参数。为此,从基于TLST理论的非均匀多导体传输线高频场耦合模型出发,对多导体传输线高频分布参数进行了研究和分析,计算出多导体传输线上的沿线单位长度高频分布参数,并将其与利用经典传输线理论计算得到的结果进行了比较,对二者的差异进行了分析,最后通过高频场线耦合算例说明了本文高频分布参数计算的正确性。
The study on the coupling of the high frequency field to multi-conductor transmission line(MTL) is a key and difficult part in EMC research,and the coupling response is closely related to the high frequency distributed parameters.Due to the quasi-TEM approximation,the classical theory of transmission line cannot be used to calculate the high frequency distributed parameters.Therefore,high frequency distributed parameters of the MTL are analyzed and calculated by the model of the high frequency field coupling to MTL which is based on TLST.Then the per-unit-length high frequency distributed parameters are calculated and compared with the result of the classical transmission line theory,and the differences between them are also analyzed.Finally,the example of high frequency field coupling to line shows the correctness of calculation of the high frequency distributed parameters in this paper.
