摘要: 把麦克斯韦方程和电磁场分解成横向和纵向分量, 导出了简明的一般性的手征等离子体填充的任意截面波导的波动方程和横向纵向场的关系式。对于部分填充手征等离子体波导, 导出了它的色散方程。这一方程的数值解给出了HE11, EH01和HE21模式的色散图。随着手征等离子体填充面积的增大, EH01模式的色散曲线向更高的频率移动。随着手征导纳的增加, 传播常数减小。Abstract: Separating Maxwell Equations and electromagnetic fields into transverse and longitudinal components, we derive brief wave equations of the longitudinal electric field and magnetic field for arbitrary cross section chiroplasma filled cylindrical waveguides. The general relations between the transverse and longitudinal field components are also derived. For a detailed and common use example, we study a partial chiroplasma filled circular cylindrical waveguide. The general relations between the transverse and longitudinal field components are also derived. For a detailed and common use example, we study a partial chiroplasma filled circular cylindrical waveguide. Its dispersion equation is derived. Numerical solution of th is equat ion gives dispersion curves of HE11, EH01 and HE21modes. Inve
