Theory and New Amplification Regime in Periodic Multi Modal Slow Wave Structures with Degeneracy Interacting with an Electron Beam
Mohamed Othman, Venkata Ananth Tamma, Filippo Capolino
We present the theory of a new amplification regime in Travelling Wave Tubes (TWTs) composed of a slow-wave periodic structure that supports multiple electromagnetic modes that can…

Giant Gain Enhancement in Photonic Crystals with a Degenerate Band Edge
Mohamed Othman, Farshad Yazdi, Alex Figotin +1
We propose a new approach leading to giant gain enhancement. It is based on unconventional slow wave resonance associated to a degenerate band edge (DBE) in the dispersion diagram…
