摘　　要：介绍了一种基于网络张量分析的电磁兼容建模和计算方法——克朗方法,此方法利用图形拓扑和张量分析,将节点、分支、网格、矩量、网络等张量空间元素同电气领域的物理概念对应起来。相应地不同物理量及其相互作用关系也可以以张量和张量方程的方式表达出来。在选定合适的求解空间后,通过拓扑空间转换就可以构建出方程,以方便后续的分析。此方法自提出以来,经过许多研究团队的拓展,已经可以用于包括传输线、孔缝在内多种情景下电磁耦合问题的计算。文章梳理了该方法的研究现状以及作者团队在此方法上的主要研究成果,并讨论了该方法的优劣及发展前景。The article introduces a modeling and calculating method of EMC called Kron's method based on tensor analysis of networks(TAN).The method makes use of graphical topology and tensorial analysis to correspond tensor spaces such as nodes,branches,meshes,moments and networks to physical concepts in electrical field.The physical concepts and their interactions can be expressed in terms of tensor and tensorial equations respectively.When a proper solution space is selected,equations can be wrote by means of topological space transformation.Since this method was proposed,it has been extended by many research teams.It can be used for the calculation of electromagnetic coupling problems in a variety of scenarios including transmission lines and apertures.This paper summarized the research advances of this method especially those of authors'team on this method.The advantages and disadvantages of the method and its development prospects are discussed.
