Abstract :
A sine waveguide traveling-wave tube with cylindrical electron beam tunnel is proposed to amplify the terahertz wave. In this paper, the high frequency characteristics of sine waveguide with cylindrical electron beam tunnel are calculated by 3-D high frequency simulation software. From the particle-in-cell simulation results, this beam-wave interaction circuit can produce several watts ranging from 0.325THz to 0.347THz.The maximum output power is 27.6W at 0.34THz, and the corresponding gain reaches 31.4dB.
