摘要
复杂线缆束系统的电磁耦合分析,随着电磁环境的日趋复杂化,显得越来越困难。而高功率电磁辐射技术的发展,对具有复杂电缆束网络和电子设备的系统,带来了严重的电磁威胁。这从电磁攻击与电磁防护两方面,对复杂线缆束的电磁耦合分析,都提出了更加迫切的需求。由于复杂线缆束网络所涉及的几何空间的边界条件十分复杂,所以很难用时域有限差分(FDTD)或频域有限差分(FDFD)方法求解复杂线缆束网络系统的电磁耦合问题。我们在基于传输线理论,采用拓扑学中将空间按照拓扑结构进行分解的思想,建立了线缆束网络电磁耦合的拓扑模型,得出了计算复杂线缆束网络系统终端耦合电压与电流的计算方法,并给出了仿真计算实例用以验证电磁拓扑法处理线缆网络电磁耦合效应的有效性。
The analysis of electromagnetic coupling of complex cable bundle system is becoming more difficult with the increasing complexity of the electromagnetic environment. The development of high power electromagnetic radiation technology brings serious electromagnetic threat to those which have complex cable bundle systems and electronic equipment systems. Related to the electromagnetic attacks and electromagnetic protection, there is an urgent need in the aspect of analysis of electromagnetic coupling of complex cable bundle system. Due to the complex geometrical space boundary conditions of complex cable bundle system, it is hard to solve this problem using methods such as the finite difference time domain method（FDTD） and the finite difference frequency domain method（FDFD）. Based on the transmission line theory, we use the decomposition skill according to the topology structure to build up a topological model of electromagnetic coupling of complex cable bundle system, and we obtain a method to calculate the terminal voltage and current of the system. We present some simulation examples to verify the availabil ity of electromagnetic topology method in dealing with the electromagnetic coupling effect of cable network.
