摘要

Based on the analytical solutions of the wave equations in the elliptical-cylindrical coordinate system, the propagation characteristics of hollow elliptical waveguide for THz Radiation are investigated, and then the mode characteristic equations are also given. Our results show that the mode characteristic equations of a circular waveguide can be treated as a special case of an elliptic waveguide. The propagation characteristics are numerically simulated depending on the refractive index of dielectrics films and the eccentricity of the elliptic waveguide. The cutoff wavelengths of guided modes in the elliptic waveguide are also presented.
