Propagation Characteristics of Metal Circular Waveguide Filled with Multilayer Reciprocal Chiral Media

  • 摘要: 采用分离变量法,导出了填充多层互易手征介质的圆波导的模式特征方程,进而可得填充普通介质的圆波导的模式特征方程.为揭示填充多层互易手征介质圆波导的传播特性,给出了填充1层和2层互易手征介质圆波导部分模式的色散特性数值计算结果.结果表明,影响圆波导传播特性的主要因素是互易手征介质的折射率;当互易手征介质的磁导率变化,而折射率、手征参数和2层介质的半径之比不变时,其归一化截止频率明显变化;当2层互易手征介质参数不变,改变它们的半径之比时,对其低次模归一化截止频率影响很小,因此,想通过改变2层互易手征介质的半径之比达到显著改变其低次模归一化截止频率和归一化带宽不可取.
