Abstract :
A novel slow-wave structure (SWS), created for THz vacuum tubes, based on two parallel corrugations in a rectangular waveguide, realizes the conditions for a quasi-cylindrical field distribution, to support the interaction with a circular beam. A design method for THz TWT including the proposed SWS is presented based on a 2-D non-linear in-house code. Validation by 3-D particle-in-cells (PIC) simulator confirms the effectiveness of the method.
