Abstract :
We have studied the electromagnetic properties of a bi-helix slow wave structure surrounded by an azimuthally conducting screen formed by metal rings with and without capacitive gaps. The dependence of phase velocity on frequency and on the geometric parameters of the rings were measured on prototypes and analyzed. Novel designs of the bi-helix SWSs with circular metallization on the diaphragm supports are proposed.
