The interaction circuit for the V-band high-power traveling-wave tube (TWT) was designed by employing the folded-waveguide slow-wave structure and a 3∶1 aspect-ratio sheet electron beam as the beam-wave interaction circuit. The effect of the sheet-beam channel on the high frequency properties was analyzed, and the optimized structural parameters were obtained under the consideration of dispersion and impedance. A 3-D circuit model of the sheet-beam folded-waveguide TWT was constructed and the beam-wave interaction of this circuit was simulated using the CST particle studio. From our calculations, the sheet-beam folded-waveguide TWT can produce output power of over 160 W with the gain over 34.7 dB ranging from 58 GHz to 62 GHz, when the cathode voltage and beam current are set to 17 kV and 150 mA respectively.
