摘要：
A dual-beam rectangular ring-bar (DBRRB ) slow wave structure (SWS), which is with a planar structure 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 characteristics are analyzed by using computer simulations. Wide bandwidth input-output structures adopting tapered structure 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 stable operation.
