Abstract :
A Ka-band high power sheet beam backward wave oscillator (BWO) has been presented in this paper. In which the double-grating rectangular waveguide is used as the slow wave structure. A high power sheet beam with cross section 30mm×1mm is produced by a thin cathode. The output power exceeds 35 MW at 31.1 GHz. The beam-wave interaction efficiency is about 14.7%.
