A no¨el one-dimensional Lagrangian simulation of beam᎐wa¨e interaction in helix tra¨eling-wa¨e 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__‐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 “syn
## Abstract We present performance improvement in InP traveling‐wave modulators (TWMs) using a periodic ion implantation on coplanar waveguide. Fabricated TWMs show the successful velocity and impedance tuning with return loss of lower than −12dB and reduced effective microwave refractive index of
