Abstract: 

Classification of electronic oscillators and amplifiers has been performed based on the ratio between directions of the kinetic energy of electrons and electromagnetic energy flows. It is shown that management of electromagnetic flows, such as through the use of natural diffraction spread and with various modifications of Bragg structures, is an effective method to synchronize the radiation of electron beams with transverse size significantly exceeding the wavelength.

Key words: 
Electronic oscillators and amplifiers
spatial coherence of radiation
diffraction divergence
Bragg structures
two-dimensional distributed feedback
