Three-Way Serpentine Slow-Wave Structures with Stationary Inflection Point and Enhanced Interaction Impedance
Robert Marosi, Tarek Mealy, Alexander Figotin +1
We introduce two novel variants of the serpentine waveguide slow-wave structure (SWS), often utilized in millimeter-wave traveling-wave tubes (TWTs), with an enhanced interaction i…

An Accurate Analytic Model for Traveling Wave Tube Dispersion Relation
Ahmed F. Abdelshafy, Filippo Capolino, Alexander Figotin
Abstract -- We construct an analytical model for the dispersion of the hot modes in a traveling wave tube (TWT) based on the Lagrangian field theory, upgrading its constants to be…
