| Abstract: | In this paper, the backward wave transportation of 220GHz folded waveguide （FWG） circuit was investigated. Focusing on 220GHz backward wave oscillator （ BWO）, and using theory and numerical simulation methods, research on cold characteristics and design the high frequency structure of 220GHz BWO. The parameters of structure and relevant simulation results have presented. The study shows the BWO can achieve power about 0.5W at 220GHz with considering lossless, and it can tunes fully and rapidly over wide band （30GHz） of frequencies by adjusting the beam voltage from 5. 5kV to 12Kv. |
