Longitudinal dielectric rods in helix traveling-wave tubes (TWTs) contribute to the determination of the performance. A study on nonrounded rectangular rods that exhibit improved dielectric loading with respect to typical rectangular rods is proposed. The expressions for computing the effective diel
A noยจel one-dimensional Lagrangian simulation of beamแwaยจe interaction in helix traยจeling-waยจe tubes is introduced in this paper. Unlike the traditional transmission-line coupled-mode Lagrangian analysis, direct electromagnetic coupling of the electric field to the RF signal from the Fourier harmoni
## Abstract An __n__โdielectric tube prototype structure consisting of a helix surrounded by adjoining dielectric tubes in an overall envelope was studied by HFSS for flatโtoโnegative dispersion characteristics needed for wideband travelingโwave tubes. The prototype structure obtained was then โsyn
