Resonant beam-excitation as a mechanism for the outputting of radio waves from ionospheric waveguides
Abstract
Consideration is given to a mechanism for the outputting of energy from an ionospheric wave channel based on resonant beam-excitation under the effect of periodic disturbances of electron density. An analysis is presented of the dependence of resonance characteristics on the relationship between initial phases of beam trajectories and inhomogeneities. Since the amplitude of resonant trajectory oscillations is significantly determined by the length of the resonance region, the q-factor of the resonant excitation depends significantly on the horizontal gradients. Regions of the ionosphere where the periodic component exceeds the remaining variations of permittivity are found to be optimal for the proposed energy-release mechanism.
