The existing input structure for confocal waveguide is narrow-banded. Thus a quasi-optical input structure for 0.4 THz confocal waveguide gyro-TWT is designed based on Gaussian transformation, and the input mode is HE06 mode. This structure is composed of a corrugated waveguide mode converter, Gaussian transformation mirrors and a receiving antenna. The structure is validated through 3D electromagnetic simulation. The simulation result indicates that, the input efficiency exceeds 50% in the 8 GHz working band of the gyro-TWT and the highest efficiency is 68%.
