| 摘 要： | 对大气中激光等离子体通道的传播终端特性进行了研究。建立了大气中激光等离子体通道的近似电磁模型,基于圆柱坐标系中纵向分量所满足的波动方程,给出了纵向场与横向场的关系,由边界条件导出了大气中激光等离子体通道的特征方程。特征方程的数值解获得了相应色散曲线。

| Abstract: | The propagation properties of laser plasma channel in air were studied in this paper.The near electromagnetic model of laser plasma channel in air was established.The relations between the transverse components and longitudinal ones of electromagnetic fields in circular cylindrical coordinate were given out based on the wave equations for the longitudinal components in circular cylindrical coordinate.The strictest characteristic equation of laser plasma channel in air was deduced by applying the boundary conditions of electromagnetic fields.The dispersive curves were acquired by numerical solving the characteristic equation. |
