摘　　要：为了解时谐场圆极化波斜入射时在分界面处的传播极化特性,通过解析理论推导并结合数值计算,分析了在不同条件下反射波、透射波和合成波的表达式。发现反射波可变为椭圆极化波、线极化波或反旋向的圆极化波;合成波变为椭圆极化波,在不同方向上呈不同分布;透射波可变为椭圆极化波、反旋向的圆极化波或消失呈表面波。所得结果对卫星通信的极化匹配等应用领域具有理论参考价值。In order to understand the propagation and polarization characteristics of the circularly polarized wave when it occurs oblique incidence at the interface,the expressions of reflected wave,transmitted wave and synthesized wave under different conditions are analyzed by analytical theory and numerical calculation.The result shows that the reflected wave can change its polarization state to elliptical polarization,linear polarization,or just changes its polarization handedness,the synthesized wave becomes elliptically polarized and exhibits different wave distributions in different directions,and the transmitted wave either disappears or becomes a surface wave or elliptical polarization wave,or just changes its polarization handedness.These findings provide theoretical insights for the polarization matching of satellite communication and so on.
