Novel Sawtooth Structure Loading to Mitigate Mode Competition in a 346 GHz Backward Wave Oscillator

摘要

A novel approach to mitigate mode competition and improve stability in a 346 GHz Backward Wave Oscillator (BWO) by loading a copper sawtooth slow wave structure (SWS) is proposed. The effects of mode competition, and the sawtooth structure loading effects are discussed. CST simulation has been used to verify the analysis and test of the stability of those circuits.
