0.22THz Double-Beams Staggered Double-Blade Backward Wave Oscillator

This paper proposes a staggered double-blade slow-wave structure (SDB-SWS) with two circular electron beams. At the same time, a slow-wave structure with the working frequency of 220GHz is designed. The particle in cell (PIC) simulation of the proposed slow-wave structure was carried out, and the output power of 41W was obtained at the operating voltage of 23.8kV and the single electron beam current of 35mA.
