Low Starting Electron Beam Current in Degenerate Band Edge Oscillators
Mohamed A. K Othman, Mehdi Veysi, Alexander Figotin +1
We propose a new principle of operation in vacuum electron-beam-based oscillators that leads to a low beam current for starting oscillations. The principle is based on super synchr…

Giant Amplification in Degenerate Band Edge Slow-Wave Structures Interacting with an Electron Beam
Mohamed A. K. Othman, Mehdi Veysi, Alexander Figotin +1
We propose a new amplification regime based on synchronous operation of four degenerate electromagnetic (EM) modes in a slow-wave structure and the electron beam, referred to as su…
