| Abstract: | A dual-beam rectangular ring-bar(DBRRB)slow wave structure(SWS),which is with a planar struc?ture and is suitable for micro fabrication,is proposed for W-band traveling-wave tubes(TWT).Supported by a pair of T-shaped dielectric rods,the RRB SWS is fit for dual-sheet beam operation.The high frequency character?istics are analyzed by using computer simulations.Wide bandwidth input-output structures adopting tapered struc?ture and step waveguide are designed.Hot-test performance of the RRB SWS is investigated by means of Particlein-cell(PIC)simulations.A solenoid magnetic field of 0.6 T is adopted to focus the sheet beams with voltage and current of 11.2 kV and 0.12 A.The saturated output power of 56.7 W at 94 GHz is obtained at the output port,corresponding a gain of 27.4 dB.In addition,an attenuator is added to suppress oscillations and achieve sta?ble operation. |
