P2-3: Exploration of a broadband 'semi-vane' helical SWS

Abstract

Slow-wave characteristics of a broadband 'semivane' helical SWS have been studied using 3D electromagnetic modeling in CST-studio. The geometry has shown promises for better broadbanding potential compared to a conventional segment loaded configuration. Also, the results have shown that placement of segments closer to the support rods provides a better negative dispersion. © 2010 IEEE.
