摘要:

对等离子体中电磁波传播的平板几何模型进行了修正, 讨论了离子对电磁波在大气压均匀非磁化弱电离等离子体中的反射、吸收和透射等传播特性的影响。数值分析的结果表明: 大气条件下, 离子对电磁波在均匀非磁化弱电离等离子体中传播特性的影响是显著的, 同时给出等离子体对电磁波的最大吸收值和吸收宽带。

Abstract:

The effect of ions on the characteristics such as reflection, absorption and transmission of electromagnet ic waves transmitting in a part ially ionized plasma is investigated with an amendatory slab model. Numerical simulat ion of the model is presented. The numerical results indicate that the effect of ions is remarkable: the higher the relative negative ion number density, the lower is the absorption. In addition, the maximal and broadband absorptions of electromagnetic waves have been calculated.

Key words: Ions, Electromagnetic waves, Characteristics
