Gyrodevices as Power Sources of Electromagnetic Waves in the Microwave Band

摘要

The evolution of gyrodevices (generators and amplifiers) where curvilinear electron beams interact with non-slow electromagnetic waves has been reviewed. The material presented covers stages of the development of gyrodevices during the 50 years from the time of their conception till the present time when devices of this class have been qualified as the most powerful VD in the millimeter wave band.
