Abstract :
Slow-wave characteristics of a broadband `semi-vane´ 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.
