An approximate nonlinear theory of double-stream instability

An approximate nonlinear theory of double-stream interaction is built. Based on this theory, calculation for double-stream ampli?er gain was performed. It was shown, that 40 dB ampli?cation can be obtained.

Two-stream instability – linear and nonlinear microwave phenomena

This article is the first of two parts of the review devoted to the phenomenon of two-beam instability in microwave electronics. The main goal is to cover as much as possible the most complete list of papers on various models and methods of analysis of the two-beam instability. The first part contains papers which, in our view, most fully describe the development of ideas of two-stream instability in microwave electronics.

Two-stream instability – linear and nonlinear microwave phenomena

This article is the second part of the review of works devoted to the phenomenon of two-stream instability in microwave electronics. As it is known, a problem of creating devices operating in the terahertz frequency range is a rather actual today. Although there are many devices that can generate or amplify signals in this range, most of them refer to extremely powerful relativistic devices. At the same time there is a lack of compact medium power devices. In recent years, models based on the interaction of two electron beams appear in the papers of foreign research groups even more often.
