P2-6: Analysis of a ridge-loaded rectangular folded-waveguide SWS

A ridge-loaded E-plane rectangular folded-waveguide slow-wave structure has been proposed and analyzed using a simple quasi-TEM analysis for the dispersion and interaction impedance characteristics, including the effects of the beam-hole discontinuity. The analysis has been validated against the approximate parametric analysis and the 3D electromagnetic modeling using CST Microwave Studio. The analysis has been used for demonstrating the efficacy of the ridge-loading on broadbanding of the structure.
