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

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.
