| 摘 要： | 提出了一种用于高功率微波武器系统的光致大气等离子体通道天线(PCA),并分析了PCA所传播一般模式的传播特性.建立了PCA的近似电磁模型,从广义柱坐标系下纵向分量所满足的波动方程出发,在广义柱坐标系中给出了纵向场与横向场的关系,利用边界条件导出了PCA严格的特征方程,并通过在极限条件下,将本文结果与文献已有结果的对比,验证了文中所导结果的正确性和有效性.最后,数值计算了该天线的色散曲线,重点讨论了传播常数随等离子体参数、通道尺寸和运动速度的变化,为该天线的研制打下坚实的理论基础.

| Abstract: | In this paper,a laser induced air plasma channel antenna(PCA) for high power microwave weapon is presented,and the dispersive characteristic for normal modes of PCA is analyzed.An approximate electromagnetic model of PCA is created.Starting from the wave equations for the longitudinal components in generalized cylindrical coordinate,the relations between the transverse components and the longitudinal ones of the electromagnetic fields are given.The strict characteristic equation of PCA is deduced by applyin... |
