| 摘 要： | 本文首先引入一种新型双各向异性波导结构;给出了这类复杂波导中横向场分量的纵向场表示式以及纵向场分量满足的一组耦合模方程;重点分析了具有不同电磁参数的双各向异性介质中心加载时,金属圆柱形波导中混合模的分裂效应,色散特性和场分布。结果表明,由于多个电磁参数的引入,双各向异性波导具有一般各向异性和双各向同性波导结构所没有的新奇特性。

| Abstract: | A new kind of bianisotropic waveguide structure is introduced. In such complex waveguide, the transverse field components can also be expressed in terms of their longitudinal electric and magnetic fields, and a set of coupled mode equations is derived. The bifurcation effect, dispersion characteristics as well as field distribution of hybrid modes in bianisotropic central loaded-metallic circular waveguide are investigated. The numerical results show that because of the introducing of many electromagnetic parameters, bianisotropic waveguides possess some features, which can be used to design novel microwave, millimeter wave and optical devices. |
