| Abstract: | Gyro-Backward wave oscillator （Gyro-BWO） has great practical prospects as a frequency tunable high-power terahertz radiation source device. According to the Gyro-BWO linear theory, the arti-cle designs an operating frequency of 220 GHz quasi-optical waveguide Gyro-BWO. By using independent research and development of three-dimensional particle simulation software CHIPIC, its operating charac-teristics are numerically simulated and analyzed. Simulation result shows that the Gyro-BWO can obtain 14kW power output. As output power great than 5 kW, the tuning bandwidth is over 1 GHz. |
