中文摘要：

为了克服现有高功率微波武器天线的不足,提出了一种用激光引导电磁脉冲(EMP)的思想,简单阐述了该思想的具体实现方法,根据其工作原理,建立了激光引导电磁脉冲的电磁模型,引入了矢量位函数,并结合边界条件导出了激光引导电磁脉冲传播的模式色散方程,给出了相应的近似解表达式。分析了激光等离子体通道周围为有耗气体媒质时激光引导电磁脉冲传播的一般模式,重点讨论了传播常数随等离子体参数和周围介质参数的变化。在特殊条件下,将文中导出的结果与文献所给出的结果对比,吻合较好。分析结果表明,通过控制等离子体的频率可以达到控制激光引导电磁脉冲传播特性的目的。

英文摘要：

In order to solve the problems existing in the current antenna for high power microwave weapon, the idea of laser guiding electromagnetic pulse (EMP) is presented. The concrete realization method of the idea is simply described. The near electromagnetic model of laser guiding EMP is created based on the operating principle. The vector potential functions are introduced, the dispersive equations of modes for laser guiding EMP is deduced by applying the boundary conditions of electromagnetic fields, and their...
