摘　　要：提出了一种用于多层电磁屏蔽条件下分析系统电子器件之间相互耦合的电磁拓扑模型。将该模型与求第k最短路算法结合,得出在不同频率范围下求从源点到终点屏蔽系数小于规定值路径的算法,得到需要改进的电磁耦合路径。该算法是通过对第k最短路算法修改而得到的,不需要求最小树和时间复杂度。仿真实验证明该算法是有效的,可以用于大型复杂电子系统耦合问题的分析。An electromagnetic topological model used to analyze the interaction of the different electrical components is presented. Combining this model with the algorithm which may find the k^th shortest path, an algorithm that can find the paths whose shielding electromagnetic values from source node to destination node are less than prescribed value under different frequency range is obtained. The electromagnetic coupling paths needed to be improved can be got with this algorithm.
