Comparison of theoretical results of the dispersion and interaction impedance with those of equivalent circuit, simulations and experiments for the double slot coupled cavity slow wave structure in TWT

摘要

A theoretical model was presented for the double slot coupled cavity slow-wave structure (CCSWS) with arbitrary staggered angle between two adjacent walls in an abstract published by the authors in last year's IVEC. In this abstract, this model is validated by comparing its results of two typical structures, one operating in Ka-band with in-line slots and the other operating in X-band with staggered slots, with those obtained by the equivalent circuit model, the simulation software Ansoft HFSS code and the experimental data.
