【摘要】：场线耦合问题是电磁兼容分析与电磁效应评估中的重要课题。经典场线耦合模型受限于准TEM波近似,在较高频率时将导致不可接受的模型误差。传输线超理论(TLST)建立了高频场线耦合模型,解决了经典场线耦合模型的困难。基于TLST介绍了非均匀多导体传输线的高频场线耦合模型,提出了三种不同终端负载情况下对应边界条件的设置方法。最后通过具体算例对比了高频模型和经典模型以及全波分析计算结果,证实了高频场线耦合模型的普遍适用性、边界条件设置的有效性和数值实现过程的准确性。
[Abstract]:The field line coupling problem is an important subject in electromagnetic compatibility analysis and electromagnetic effect evaluation. The classical field-line coupling model is limited by the quasi-TEM wave approximation and will lead to unacceptable model errors at higher frequencies. The transmission line supertheory (TLST) has established the high frequency field line coupling model and solved the difficulty of the classical field line coupling model. Based on TLST, the coupling model of high frequency field lines for non-uniform multi-conductor transmission lines is introduced, and three methods for setting boundary conditions under different terminal loads are proposed. Finally, the results of high frequency model, classical model and full wave analysis are compared with each other, which proves the universal applicability of high frequency field line coupling model, the validity of boundary condition setting and the accuracy of numerical realization.
