等离子体共振表面波的分析

Analysis of Surface Wave with Plasma Resonance

研究具有轴向线性密度特性的非均匀圆柱冷等离子体的表面波,得到了碰撞等离子体时纯表面波在横磁模式下的实频率、衰减速率和特征函数,并且考虑了等离子体共振的情况.结果表明,在等离子体共振时的位置处,特征函数有极大值.

Surface waves are studied in axially non-uniform cylindrical cold plasma with a linear density profile. The real frequency, damping rate, and eigenfunction for the transverse magnetic mode in pure surface waves are obtained for collisional plasmas, where the plasma resonance is taken into account. It is shown that the eigenfunction peaks at the position of the plasma resonance layer.
