General relations of the cyclotron and synchronous oscillations and
waves of the electron beam are discussed in a form of short review.
Development of modern microwave communication, radio and radar facilities places additional stringent requirements upon the different microwave devices.
During last several decades mainly in Russia active and successful work is being carried on to create new electron beam microwave devices based on cyclotron and synchronous waves use and complying with the present-day requirements.
The operation of these devices is based on the principles of transverse grouping of the electron beam in the longitudinal magnetic field. In contrast to conventional longitudinal grouping of electrons into dense bunches, this principle employs the Lorenz force as an elastic force and leads to spatial distortion of the electric beam without electron bunches being formed. In this way it is possible to considerably overcome the fundamental restrictions, which are characteristic of longitudinal grouping devices (both vacuum and solid-state ones) and are associated with non-linear influence of the space charge fields upon the process of the input signal amplification, thereby laying the basis for developing new microwave devices with essentially improved characteristics.
Authorís experience in discussions of these principles both with domestic and foreign specialists has disclosed the expediency of the preparation of this article.
