分析传输线网络的电磁耦合问题

现代当微波辐照一个雷达接收机时，将对雷达接收机产生“带内”干扰但是当入射电
磁脉冲作用于系统中的某一设备时，系统中的其他设备也很可能会受到影响。本文采用传输线网络拓扑模型来表示复杂系统，并运用BLT 方程来分析传输线网络对电磁激励的响应。最后结合三种典型的系统结构进行了举例分析。

Abstract: Modern electric devices always work in complicated electromagnetic environment. Although some shield measures, when an incident electromagnetic pulse acts on a certain device in the system, other devices may be affected. In this paper, a complicated system is represented by a transmission line network topology model, and its response to the electromagnetic excitement is analyzed using BLT Equation. And this paper gives an example of  three typical system configurations.
