Distributed generator with extended interaction on field emitter arrays

Abstract

A possibility for designing a distributed MW generator on field emitter arrays (FEAs) has been studied which involves a waveguide interaction system (WIS) as a circular distributed resonator (CDR). This generator was shown to be capable of operating in the millimeter wavelength band with low voltages and beam current densities and to provide an efficiency to 20%. The electrical tuning of the generator in frequency can achieve 30% for one of its versions.
