Abstract :
A theoretical model for the arbitrarily-shaped groove staggered double-grating array waveguide (SDGAW) slow-wave structure (SWS) is used to calculate the characteristics of dispersion and coupling impedance for a step-shaped staggered double-grating slow wave structure for W band TWT application. The results are compared with those obtained by CST-MWS code simulation.
