METHOD OF AMPLIFICATION OF ELECTROMAGNETIC OSCILLATIONS IN ELECTRONIC DEVICES Russian patent published in 1995 - IPC

FIELD: electronics. SUBSTANCE: method of amplification of electromagnetic oscillations lies in formation of axially symmetric beam, in synchronous interaction of electron beam in outlet section of electrodynamic system with its normal waves which azimuthal distribution or polarization differs from azimuthal distribution or polarization of normal waves of inlet section, in bringing of amplified signal out of output section of electrodynamic system. Method is realized in device given in description of invention. EFFECT: prolonged duration of output radiation in powerful devices with maintenance of high amplification factor. 3 dwg
