  • The vacuum electronic device with sheet beam driven rectangular waveguide gratings is a small size, high gain, easy to fabricated device. It has potential to produce high power terahertz radiation. This paper proposes a novel sheet beam high power device. The dispersion characteristics of the rectangular waveguide grating slow wave structure are analyzed. The coupling impedance is studied in detail. And a W-band sheet beam rectangular waveguide grating backward-wave oscillator(BWO) is simulated. The optimized BWO can produce 42 MW at frequency 86 GHz, driven by a 200 kV, 2kA, 24 mm0.5 mm sheet electron beam. The efficiency is 10.5%.
