Findings

Generation intensity depends on grating length

Optimal grating length for maximum output identified

Experimental validation of theoretical models

Abstract

Experimental studies of the backward wave oscillator with a ''grid'' diffraction grating that is formed by a periodic set of metallic threads inside a rectangular waveguide are proceeded with study of the generation intensity as a function of the grating length.
