In the second volume of the book "Non-stationary and chaotic processes" such modern areas of research in radiophysics are considered. Electronics and non-linear dynamics as the development of new principles for the generation of chaotic microwave signals and the creation on their basis of sources of broadband noise-like signals for modern information and telecommunication systems various methods of controlling chaotic oscillations in beam-plasma systems, synchronization (including chaotic) in ultra-high frequency electronics , nonlinear wave processes in systems with magnetostatic waves and in the propagation of wave beams. For physicists of various specialties interested in the processes of interaction of electrons with electromagnetic fields, for scientists, graduate students and engineers conducting research in the field of vacuum microwave electronics, radiophysics, radio engineering and plasma physics It can be useful for senior students of relevant specialties.
