Super-exponential Amplification of Wavepacket Propagation in Traveling Wave Tubes
Kasra Rouhi, Filippo Capolino, Alexander Figotin
We analyze wavepacket propagation in traveling wave tubes (TWTs) analytically and numerically. TWT design in essence comprises a pencil-like electron beam in vacuum interacting wit…
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…
Parametric Modeling of Serpentine Waveguide Traveling Wave Tubes
Kasra Rouhi, Robert Marosi, Tarek Mealy +2
A simple and fast model for numerically calculating small-signal gain in serpentine waveguide traveling-wave tubes (TWTs) is described. In the framework of the Pierce model, we con…
Analytical Solution for Space-Charge Waves in a Two-Stream Cylindrical Electron Beam
Tarek Mealy, Robert Marosi, Kasra Rouhi +1
We present an analytical method to compute the wavenumbers and electric fields of the space-charge-wave eigenmodes supported by a two-stream electron beam, consisting of a solid in…
