In this paper, microwave propagation through an inhomogeneous drifting collisional magnetized plasma slab is theoretically analyzed. The electron density and collision frequency have sinusoidal distribution. The electromagnetic wave has right-handed circular polarization and normally incident on the plasma surface. The reflectance, transmittance, and absorbance coefficients of this inhomogeneous plasma have been calculated by dividing the total slab into several sub-slabs so that electron density and collisional frequency parameters are considered constant in every sub-slab. Here the external magnetic field is uniform and its direction is along the inhomogeneity and perpendicular to surfaces of the plasma slab. Moreover, the plasma layer is moving with a non-relativistic constant velocity along the external magnetic field. The effects of frequency of the incident wave, cyclotron frequency, collision frequency, and velocity of the slab on the transmission, absorption, and reflection of the electromagnetic wave from the plasma layer are simulated. Results show that in this inhomogeneous magnetized plasma slab, reflection and absorption of the wave can be controlled by the external magnetic field and collision frequency. In low collision frequencies, the plasma slab behaves like an opaque or transparent medium when the frequency of the incident wave is lower or higher than the plasma frequency, respectively, whereas by increasing the collisional effects, the transmission of the high-frequency electromagnetic wave decreases and the significant part of the wave energy is absorbed by the plasma medium. Furthermore, the electromagnetic wave transmitted from this inhomogeneous slab can almost be vanished by adjusting the strength of the external magnetic field.

碰撞频率和密度不均匀的运动碰撞磁化等离子体平板中圆极化电磁波的反射，透射和吸收

从理论上分析了微波通过非均匀漂移碰撞磁化等离子体平板的传播。电子密度和碰撞频率具有正弦分布。电磁波具有右旋圆极化并且通常入射在等离子体表面上。通过将整个平板分成几个子平板，可以计算出这种非均匀等离子体的反射率，透射率和吸收系数，这样，在每个子平板中电子密度和碰撞频率参数就被认为是恒定的。在此，外部磁场是均匀的，其方向沿不均匀性且垂直于等离子体平板的表面。此外，等离子体层以非相对论的恒定速度沿着外部磁场移动。模拟了入射波的频率，回旋加速器频率，碰撞频率和平板速度对等离子体层电磁波的传输，吸收和反射的影响。结果表明，在这种非均质磁化等离子体平板中，波的反射和吸收可以通过外部磁场和碰撞频率来控制。在低碰撞频率下，当入射波的频率分别低于或高于等离子体频率时，等离子体平板的行为就像不透明或透明的介质，而通过增加碰撞效果，高频电磁波的传输会降低波能量的很大一部分被等离子体介质吸收。此外，
