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…

Demonstration of a Degenerate Band Edge in Periodically-Loaded Circular Waveguides
Mohamed Othman, Filippo Capolino
We demonstrate the existence of a special degeneracy condition, called degenerate band edge (DBE), between two Bloch modes in periodically loaded circular all-metallic waveguides a…
