| 摘 要： | 基于分层传播原理提出了一种计算电磁波在非均匀磁化等离子体层中反射率和吸收率的模型,并数值分析了等离子体密度与碰撞频率,以及背景磁场强度对电磁波的反射和吸收特性的影响.研究表明:该法所得结果与文献的传播矩阵(SMM)法一致.数值分析发现:低密度高碰撞频率等离子体可减少等离子体层对入射波的功率反射;高密度高碰撞频率等离子体可改善其对入射波的功率反射宽频带吸收特性;背景磁场强度可明显改变等离子共振吸收频段.

| Abstract: | A model for calculating the reflection and absorption power of electromagnetic wave in non-uniform magnetized plasma slab was given out based on layer propagation theory in this paper.The effects of the electron number density,collision frequency and external magnetic strengths on reflection and absorption were discussed by numerical method.The study showed that the result gained by this method was well agreed with that acquired by the scattering matrix method(SMM) in reference.The numerical computation fou... |
