An analytical model is presented in this paper for a coupled cavity slow-wave structure (CCSWS) with double in-line slots, also known as the “Chodorow” structure. Under matching boundary conditions in conjunction with Green’s function techniques and moment method (MOM), the formulae for discussing the high frequency characteristics of the SWS, including dispersion and interaction impedance, are given. The frequency characteristics for an X band Chodorow structure are calculated using these formulae, Ansoft HFSS code and equivalent circuit model. Results show that the dispersion and interaction impedance obtained with the formulae are in good agreement with those calculated by Ansoft HFSS code, while its calculation rate is more rapid than that with the code, and its calculation precision is higher than that with equivalent circuit method, which is helpful for the engineering design.-
