电磁脉冲（EMP）会对电子设备、器件以及系统的信号线路造成干扰、潜在性失效或永久性损伤,而传输线及其网络正是其主要的能量耦合通道,为研究注入式电磁脉冲对传输线网络的耦合规律,以环形网络和树形网络两种常见网络为研究对象,运用电磁拓扑理论与BLT方程,研究电磁脉冲在传输线网络中的时域响应。首先推导了传输线网络BLT方程并进行求解,建立了树形结构和环形结构传输线网络的电磁拓扑模型,在运用BLT方程求解网络结点响应的过程中,提出了先求解网络传递函数而后结合时域卷积的计算方法,对网络结点的时域响应进行了仿真计算。通过树形网络和环形网络的电磁脉冲瞬态响应的实验研究,验证了所采用的理论和仿真分析方法的有效性,这些结果对进一步研究传输线网络对电磁脉冲的响应规律和防护技术具有指导意义。

To investigate the coupling mechanism between electromagnetic pulse (EMP) and transmission line network, we took two familiar networks, tree networks and annular networks, as examples, then, using electromagnetic topology theory and BLT equation, we studied transient responses of networks to EMP. Moreover, we analyzed the foundation and solution of BLT equation, and established an electromagnetic topology models of tree and annular networks. By using BLT super-matrices equation of networks, the node responses of networks were gained. A new calculation method, which combines the transfer function of network with convolution in time, was adopted in time-domain simulation, and the method was verified by experiment. The results can provide a new timedomain simulation method and experimental base in the research of networks transient responses and put forward the effective protective measures against EMP.
