An n ‐dielectric tube prototype structure consisting of a helix surrounded by adjoining dielectric tubes in an overall envelope was studied by HFSS for flat‐to‐negative dispersion characteristics needed for wideband traveling‐wave tubes. The prototype structure obtained was then “synthesized” to obtain a wedge‐shaped n ‐step staircase dielectric support structure for a helix. © 2002 John Wiley & Sons, Inc.
