The terahertz (THz) spectrum technique has become an important research content of electromagnetic field in recent years. Folded waveguide backward wave oscillator (BWO) is suitable to be used as THz high-power electromagnetic radiation source. Because it can realize electronic tuning within a wide frequency band and doesn’t require pre-stage source amplifier. In this paper, the high frequency characteristic, the transmission characteristics, and the particle beam wave interaction characteristics of the structure of folded waveguide BWO have been analyzed, and it is utilized to design geometry parameters of 650GHz folded waveguide slow-wave-structure (SWS). The design is been validated by particle beam wave interaction simulation experiments. The experiment results show that the output is over 1.7W within 42GHz bandwidth, and the electron efficiency can exceed 1%.
