Abstract
Based on the mode-coupling method, a comparative study is carried out for the frequency response of the double-sinusoidal ripples structure operating at 0.35 THz frequency. The results show that compared to the single-sinusoidal ripples structure, the bandwidth of the competing mode and the operating mode are narrowed by employing the double-sinusoidal ripples, and the Q-factor becomes greater. These peculiarities are favorable to constructing a single higher-order mode and high-Q resonator operating at THz frequency.
