Wideband Glide-Symmetric Slow-Wave Structure for Millimeter-Wave Sheet Beam TWTs
Robert Marosi, Muhammed Zuboraj, Filippo Capolino
We introduce a slow-wave structure (SWS) for a millimeter-wave sheet-beam traveling-wave tube (TWT) with wide bandwidth. The wideband and stable operation is enabled through the to…

Small-Signal Model for Inhomogeneous Helix Traveling-Wave Tubes using Transfer Matrices
Robert Marosi, Kasra Rouhi, Tarek Mealy +2
Abstract We introduce a practical method for modeling the small-signal behavior of frequency-dispersive and inhomogeneous helix-type traveling-wave tube (TWT) amplifiers based on a…
