摘　　要：电磁波与等离子体之间的相互作用是等离子体电子学和高功率微波器件研究的重点,加载等离子体可以大幅度提高微波器件的输出功率和效率。文章提出了一种新型介质周期结构即正弦周期磁化等离子体介质结构,通过采用广义反射理论和介质边界条件严格推导出电磁波在其中传播时的左旋圆极化波和右旋圆极化波的色散方程并进行了数值计算和分析,从而研究了电磁波在该介质结构中的传播特性。The interaction between the plasma and electromagnetic wave is a focus on the study of high-power microwave devices, loading plasma is able to greatly increase the output power and efficiency of microwave devices. This paper puts forward a kind of new periodie structure of dielectric, according to the theories of generalized refleetion and medium boundary conditions, the dispersion equations of left rotary circle polarization wave and right rotary circle polarization wave in the structure were derived, the numerical calculation, and analysis were done. Through numerial calculation and analysis, the characteristics of propagation of electromagnetic wave in this structure were known.
