A new method of broad banding a helix TWT is suggested in which, instead of shaping the dispersion characteristics of helical structure by using tapered geometry dielectric helix-support rods, a two-stage dielectric loading is provided by severing th

A helical slow-wave structure consisting of a metallic helix supported by double-negative metamaterial (DNG-MTM) rods, symmetrically arranged around the helix, in a metal envelope was analyzed, considering the frequency-dependent permeability and the

A helix supported by a double-negative metamaterial (DNG-MMT) surrounding it, in a metal envelope, was field-analyzed to show that the shape of the dispersion is more sensitive to the value of the relative permittivity of the metamaterial (MMT) than
