Coalesced-mode Inductively Loaded Interdigital Structure for Broadband TWTs

Abstract

In this paper, rectangular inductively loaded interdigital-slow wave (ILID-SWS) structure is analysed using quasi-TEM approach and 3-D simulations is presented. The analysis is validated with experimentation and the structure is found to be promising in terms of bandwidth when compared with folded waveguide-SWS and millitron SWS.
