本文在柱坐标系中导出了手征等离子体波导内横向场量与纵向场量之间的关系,给出求解纵向场量的波动方程.利用波导壁上的电场边界条件,建立了手征等离子体介质填充的圆波导传播常数的特征方程,计算得到了几种低次模式的传播常数随归一化波导半径及材料参数的一系列变化曲线,分析得出了若干有意义的结论. In this paper, the relationship between the horizontal field and the vertical field in the chiral plasma waveguide is deduced in the cylindrical coordinate system, and the wave equation of the longitudinal field is given. By using the boundary conditions of the electric field on the waveguide wall, the chiral plasma A series of curves of the propagation constants of several low-order modes with the normalized waveguide radii and material parameters were calculated and some meaningful conclusions were obtained.
