A novel H-plane loaded folded waveguide slow wave structure for traveling wave tube
A novel taper H-plane loaded folded waveguide (FWG) slow wave structure (SWS) for traveling wave tube (TWT) amplifier has been presented. The high-frequency characteristics and the amplification performance have been investigated. The results implied that this structure possessed higher transverse dimension and higher efficiency than those of the traditional FWG-SWS.
