Wave processes in an open waveguide with a metal-dielectric layer

Abstract

In this paper, the linear self-consistent theory of an amplifier based on the Smith-Parsell effect is developed for a periodical metal structure in terms of metal-dielectric layer field and electron beam interaction. A dispersion equation has been obtained allowing for the analysis of the effect of the metal-dielectric layer exerted on the electromagnetic wave stimulation in such a structure. The electrodynamic amplification system has been experimentally investigated in the mm-wave range.
