TL;DR: An experimental demonstration of a strong enhancement of the interaction efficiency in a high-power relativistic backward-wave oscillator when plasma is injected is presented in this article, which is attributed to induced scattering of the electromagnetic radiation of electrons in an electrostatic field produced by the background plasma and a beam space-charge wave in the corrugated interaction region.

TL;DR: In this article, a linear theory of the excitation of electromagnetic waves in a plasma-filled corrugated-wall waveguide with an arbitrarily large sinusoidal corrugation was derived and analyzed numerically.

TL;DR: An experimental demonstration of a strong enhancement of the interaction efficiency in a high-power relativistic backward-wave oscillator when plasma is injected is presented in this article, where a linear theory of electro- magnetic wave generation in plasma-loaded corrugated wall resonators is reviewed.

TL;DR: In this article, it has been observed that an order of magnitude resonant increase in microwave output power occurs at a particular pressure of the background gas and this resonance has also been observed to be strongly dependent on the value of applied axial magnetic field.
