Abstract

Design of the staggered double vane slow wave structure (SWS) for two bands of traveling wave tube (TWT) amplifier, one for Ka-band and another one for W-band, has been presented in this paper. The high-frequency characteristics of this kind of structure were calculated by the HFSS eigenmode solver. And particle-in-cell method was carried out to investigate the amplification performance of this structure. Moreover, the experimental models, systems, and the results of this SWS for W-band TWT are exhibited in the end.
