Nonlinear model of two electron beam and testing

Non-linear nonstationary theory of two-stream amplifier has been suggested for case of co- and opposite directed beams. Non-linear theory has been compared with calculation of linear theory for both cases. Download full version

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.

For nonlinear nonstationary theory of two-stream traveling-wave tube amplifier and two-stream amplifier: general equations and some results of calculation

In the work shows a way of developing the theory of nonlinear non-stationary two-beam traveling wave tube with a codirected beams, based on the nonlinear theory of traveling wave tube with a single electron beam. The need to build a double-beam traveling wave tube theory arose from the study of two-stream amplifier. It consists of an input device, an output device and the drift space, where two electron beams interact. In the input device there is a stream of modulation, which interact with each other in the drift space due to the phenomenon of two-stream instability.
