摘要
提出了一种屏蔽计算机系统的高功率微波(HPM)效应拓扑图分析方法。实现了屏蔽系统的电磁拓扑图,分析了HPM的孔缝耦合进入腔体的极化规律,用扩展BLT方程分析了线缆在HPM辐照下能量进入屏蔽系统的规律;强调了在屏蔽电子系统HPM效应拓扑图的研究中,HPM的频率和极化是表示屏蔽系数的两个重要的效应参数,最终用以这两个参数为变量的矩阵表示了系统HPM效应拓扑图,用最短路径算法求解该矩阵,可求得从源点到终点总屏蔽系数小于一定值,需要加固的电磁耦合路径。
An electromagnetic topological model used to analyze the High Power Microwave effects on the electrical components is presented. The model, whose foundation is linear coupling, emphasizes the basic concept of Electromagnetic Topology, the coupling method in the system analysis and two parameters ： the polarization of electric field and frequency of HPM . The importance of the HPM pa- rameters are explained by the examples of slot-coupling and wire-coupling. The algorithm of graph theory is combined with and the electromagnetic coupling paths needed to be enhanced under HPM environment can be found.
