The effects of nonuniform moving plasma on the polarization properties of electromagnetic (EM) waves were theoretically studied. Taking the ${L}$ -band right-hand circularly polarized (RHCP) wave as an example, based on the nonuniform moving plasma slab moving perpendicularly to the incident wave, the relationship between the polarization properties of the transmitted wave and the normalized velocity of the nonuniform plasma slab was analyzed. The results indicate that the polarization state of the transmitted wave is closely related to the normalized velocity of the nonuniform plasma slab. When the plasma slab approaches to the incident wave, its influence on the polarization properties is greater than that away from the incident wave. In addition, when the change of the polarization state reaches the maximum, the corresponding normalized velocity is mainly determined by the incident angle and the collision frequency. Various interesting features regarding polarization properties were obtained. The results are very important for applications in space exploration.

非均匀运动等离子体对斜入射电磁波偏振特性的影响

理论上研究了非均匀运动等离子体对电磁 (EM) 波极化特性的影响。以${L}$-波段右旋圆极化（RHCP）波为例，基于垂直于入射波运动的非均匀运动等离子体板，透射波的极化性质与归一化速度的关系分析了不均匀等离子板的厚度。结果表明，透射波的偏振态与非均匀等离子体板的归一化速度密切相关。当等离子体板靠近入射波时，其对偏振特性的影响大于远离入射波的影响。此外，当偏振态变化达到最大时，对应的归一化速度主要由入射角和碰撞频率决定。获得了关于偏振特性的各种有趣的特征。该结果对于空间探索的应用非常重要。
