STUDY ON THE CHARACTERISTICS OF HYBRID MODES IN CIRCULAR WAVEGUIDES PARTIALLY FILLED WITH BIANISOTROPIC MEDIUM
部分填充双各向异性介质的圆柱形波导中混合模特性研究

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.
