Terahertz (THz) vacuum travelling wave tubes require slow-wave struc- tures (SWSs) realisable by microfabrication processes, which assure an effective interaction with the electron beam. A corrugated rectangular waveguide with the corrugation narrower than the width of the wave- guide is proposed as a slow-wave structure for THz travelling wave tubes (TWTs). A complete cold parameter analysis by a 3D electro- magnetic simulator is presented, and the validity of the structure is demonstrated
