摘要: 目前高功率微波（HPM）对电子系统的干扰和破坏问题受到了广泛的关注，可运用BLT方程解决一些HPM产生的干扰问题。通过研究一个简单的HPM干扰模型，结合BLT方程的基本形式，对传统的BLT方程进行了扩展；接着对这个干扰模型的一个数值实例进行计算，并对干扰响应进行分析。分析结果表明，扩展后的BLT方程不仅可以计算传输线上的负载响应，也能够计算空间场的响应。Abstract: The electromagnetic interaction with electric devices caused by high power microwave(HPM) is now much concerned. The BLT equation can solve some problems of electromagnetic interaction. This paper firstly introduces the formulations of the BLT equation and the parameters of the equations. Secondly it extends the conventional BLT equation through studying a simple HPM interaction model. Finally it provides a numerical example to analyze the interaction responses arising from HPM. The results show that the extended BLT equation can evaluate the propagation of the electromagnetic energy along the conductors and the electromagnetic field propagation in the space.
