摘要
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, relations between the transverse components and the longitudinal ones of electromagnetic fields in rhiroplasma waveguides are derived in a cylindrical coordinate system. The wave equations for the longitudinal components are also presented. By applying the boundary conditions on the wall of a circular waveguide, the characteristic equation for the circular chiroplasma waveguide is obtaind. Propagation constants varying with the normalized radii of the waveguide as well as the chiroplasma parameters are calculated for several lower modes. Some meaningful conclusions are deduced on the basis of numerical results.
