THE COMBINED EFFECTS OF GYROTROPY AND CHIRALITY IN CIRCULAR FARADAY CHIROWAVEGUIDES
-
摘要: 基于分離變量和Mller求根法,本文詳細(xì)地分析了均勻和非均勻法拉第手征圓波導(dǎo)中混合模的傳輸特性;揭示了模分裂、對(duì)稱和非互易性、后向波和衰減隨不同本構(gòu)參數(shù)的變化規(guī)律,而這不同于一般旋磁和互易手征波導(dǎo)情形。

Abstract: Based on the method of separating variables and Muller s calculating roots, the propagation characteristics of hybrid modes in homogeneous and inhomogeneous circular Faraday chi-rowaveguides are examined in detail. Numerical results are presented to demonstrate the effects of different constitutional parameters on the mode bifurcation, symmetry and nonreciprocity, backward-wave and attenuation of hybrid modes, which are different from the cases of ordinary gyrotropic and reciprocal chiral waveguides. -
