摘　　要：该文首先对椭圆手征波导进行了解析求解,导出了模式场解及模式特征方程,然后用数值计算的方法研究了手征参数对椭圆手征波导中导模的色散曲线和截止波长的影响,发现在椭圆手征波导中导模的第一个模式会随手征参数的增加而不同。Analytical solutions of electromagnetic fields in the elliptical chirowaveguide have been studied. The modal fields distribution and modal characteristic equations are obtained. The numerical solutions for the modal characteristic equations of lower-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.
