Preliminary design of a G-band extended interaction oscillator driven by a sheet electron beam

A preliminary design of a G-band extended interaction oscillator (EIO) driven by a sheet electron beam is presented in this paper. PIC-3D simulations reveal that an output power of about 3.1 kW can be achieved when driven by a sheet electron beam with a voltage of 31.5 kV and a current of 0.85 A. The oscillation frequency is 197.3 GHz and the electronic efficiency is about 11.6%.
