摘要: 研究了有界波电磁脉冲模拟器下短线缆效应的理论建模和实验方法。基于传输线模型计算了线缆在有界波电磁脉冲模拟器辐照下的电流响应。建立了有界波电磁脉冲模拟试验环境，其前沿时间小于5 ns,脉冲半高宽约200 ns。开展了短线缆的效应实验验证研究，短线缆负载端响应电流的测量和计算结果吻合得很好，表明应用改型有界波电磁脉冲模拟器开展短线缆效应实验在理论和实验上都是可行的。这种线缆实验方法具有效应实验空间电磁场分布规范均匀、参数指标可控、监测技术成熟等优点。

Abstract: The response of a short single-wire line excited by EMP was theoretically investigated and experimentally validated by means of an EMP simulator. A modified bounded-wave EMP simulator was developed with a rise time less than 5 ns and pulse width about 200 ns for the short line validation test. Comparison of current responses at the line termination between calculation using the transmission line theory and experimental measurement were presented. The good agreement shows that this bounded-wave EMP simulator can be used for short single-wire line experiment. This method of effects experiment has the characteristics of reasonably uniform electromagnetic field distribution in the working volume, easy adjustment of EMP experiment parameters and convenience to measure electric field and current -
