等离子体波导中电磁波的色散特性

Wave Dispersion Property in Completely plasma-filled Waveguide

本文对全部充满等离子体且有外加恒定磁场的圆柱波导的电磁波色散特性进行了分析．对原有的色散方程进行了修正．在色散图上提出了一种新的电磁波分类方法．同原有的波分类相比，这种分类更为合理．同时，通过对新的色散方程进行数值求解，发现了原有计算结果的一些错误．

In this paper,the wave dispersion property in completely plasma-filled waveguidewith definite magnetic field is analyzed. A revised dispersion equation is derived and calculated. Anew division of wave modes is given. Compared with the old division,this new division is more suitable. Also,from the numerical calculation of the new dispersion equation,some errors in former results are corrected.
