Abstract

A Backward Wave Oscillator (BWO) based on Double Corrugated Waveguide (DCW) is presented to operate at 0.346 THz. The dimensions of the DCW are defined to have high interaction impedance and low losses at a beam voltage of 13 kV. An efficient coupler with reduced length is designed to connect the DCW to WR-2 standard rectangular waveguide. Particle in Cell (PIC) simulations are performed using CST particle studio. The results show that the BWO can produce 500 mW cw output power.
