橢圓手征波導的導模特性研究

Characteristics of guided modes in the elliptical chirowaveguide

  • 摘要: 該文首先對橢圓手征波導進行了解析求解,導出了模式場解及模式特征方程,然后用數(shù)值計算的方法研究了手征參數(shù)對橢圓手征波導中導模的色散曲線和截止波長的影響,發(fā)現(xiàn)在橢圓手征波導中導模的第一個模式會隨手征參數(shù)的增加而不同。
    Abstract: Analytical solutions of electromagnetic fields in the elliptical chirowaveguide have been studied. The model fields distribution and modal characteristic equations are obtained. The numerical solutions for the modal characteristic equations of low-order modes have been investigated. Effects of chirality parameters on the characteristics such as dispersion curves and cutoff wavelengths of guided modes in the elliptical chirowaveguide are presented. The first-order mode will be changed as the chirality parameter increased.
