We consider the interaction of Gaussian pulse of electromagnetic radiation with a plasma layer located in a constant magnetic field directed along the layer boundaries. We show that, when exposed to a long pulse, the transmitted pulse amplitude decreases due to a partial reflection from the layer boundaries and the influence of electron collisions. When exposed to a short pulse, in the case where the frequencies of the waves excited in the layer are far from the transparency region boundaries, the transmitted pulse broadens due to the group-velocity dispersion. If the frequencies of the excited waves are close to the transparency boundaries, the envelope oscillations appear in the transmitted pulse tail.

我们考虑电磁辐射的高斯脉冲与位于沿层边界定向的恒定磁场中的等离子体层的相互作用。我们发现，当暴露于长脉冲时，由于层边界的部分反射和电子碰撞的影响，传输的脉冲幅度会降低。当暴露于短脉冲时，在层中激发的波的频率远离透明区域边界的情况下，传输的脉冲由于群速度色散而变宽。如果激发波的频率接近透明边界，则包络振荡出现在发射的脉冲尾部中。
