| 摘 要： | 分析了电磁波以任意角度入射到有限磁场中的激光等离子体通道天线(LPCA)时的电磁散射特性。根据LPCA的工作原理建立了其电磁分析模型，推导出广义柱坐标系下各向异性磁化等离子体中纵向分量所满足的波动方程和纵向场与横向场的关系，得到LPCA和周围媒质中的电磁场，利用边界切向电磁场连续，得出了散射系数方程。通过计算实例，将结果与文献结果比较，吻合较好。该研究结果预期可应用于高功率微波武器系统的研究。

| Abstract: | The scattering characteristic of an obliquely incident plane electromagnetic wave by laser plasma channel antenna (LPCA) in a finite magnetic field is discussed and the electromagnetic model of LPCA in a finite magnetic field is created. Using the cylindrical coordinate and anisotropic magnetized plasma model, the wave equations of the longitudinal components and the relationships between transverse and longitudinal component are derived, the electromagnetic fields in LPCA and in the medium are given, and t... |
