Feasibility of Quantum Analogues of Classical Microwave Devices on Longitudinal Interaction
Possible quantum analogues of classical powerful microwave devices (multiwave Cherenkov generator, high-power klystrons, relativistic TWT and BWO) in the interaction of multi streams of charged particles of different sign are discussed. From the standpoint link with the experiment, we have the electronpositron system with collective interaction of many macroscopic groups of particles.
Currently developing new scientific direction - gamma electronics, which investigated the interaction of the electron and positron beams with the electromagnetic field in the γ-range wavelength. Gamma-electronics study tasks and problems of production and long existence the electron-positron substance (EPS) with unique properties. The ability to manage the use of the energy of electron-positron pairs to implement the EPS and the creation microwave amplifiers and oscillators on powerful multibeam flows of slow electrons and positrons is an important problem of relativistic electronics.
IVEC was originally created in 2000 by merging the U.S. Power Tubes Conferences and the European Space Agency TWTA Workshops. Now a fully international conference, IVEC is held every other year in the U.S., and in Europe and Asia alternately every fourth year. After the successful and enjoyable meeting in Paris, France in May, IVEC 2014 will return to its beautiful U.S. location in the city of Monterey.
The Seventeenth International Vacuum Electronics Conference (IVEC 2016) helded on 19-21 April 2016 in Monterey, California. With technical co-sponsorship from the IEEE Electron Devices Society (EDS), the conference provide a forum for scientists and engineers from around the globe to present the latest developments in vacuum electronics technology at frequencies ranging from the UHF to THz frequency bands.

Periodical electrodynamic structures are widely used to create powerful electronic devices, microwave filters, antennas. A wider class of heterogeneous media and slow-wave systems (SWS) is a pseudoperiodic structure proposed for the selection of waves, including the suppression or amplification of backward waves. These are, for example, synchronous helix (Solntsev Spiral-SS), including as a special case of a logarithmic spiral, with the suppression of pseudoperiodic waveguides parasitic backward waves. The principle of constructing pseudoperiodic-layered media is similar to the principle of creating pseudoperiodic waveguides and based on a consistent change in the thickness of the media’s layers along with the change of electric permittivity and magnetic permittivity, determining the phase shift of the electromagnetic field on the layer. According to this principle, the distribution pitch of the layers and the phase of the field along the structure are selected so as to maintain the phase velocity and amplitude of the selected spatial harmonics of the field the same as in the original periodic layered media and the amplitude of the other spatial harmonics decrease; selection takes spatial harmonics (spatial selection). In the pseudoperiodic-layered media expected to get a selection of backward spatial harmonics, which is the production of media with a backward wave having the opposite direction of propagation phase and energy flow. Investigation of the properties of electromagnetic waves in pseudoperiodic-layered media and slow-wave systems opens the possibility of creating on this basis new microwave devices. Media with a backward wave in recent years attracted the attention of many researchers, because they have new unusual laws of reflection and refraction and allow to obtain focus over beams in the microwave and optical ranges. The well-known works are "metamedia" based on the use of periodic electrodynamic structures (photonic or electromagnetic crystals). This paper presents a method and a program for calculating the properties of electromagnetic waves in a pseudoperiodic-layered media. Also some possibilities of allocation of backward waves in an environment that determine the properties of propagation of electromagnetic waves are shown.
The physical effects and problems within the scientific direction "Gamma-electronics (γ-electronics)", which studies the interaction of the electron and positron fluxes with the electromagnetic field in the γ-range of wavelengths, as well as problems of production and the prolonged existence of the electron-positron substance (EPS) with extremely high stored energy released in the process of collective slow annihilation have been concidered. We discusses the possible quantum analogues of classical high-power microwave devices in the interaction of charged particles multipath different sign. The basic stages of work, corresponding to the possible experiment in gamma-electronics with streams of electrons and positrons have been indicated.
The technique of resonance effects analysis in the quantum exchange interaction of the electron and positron flows is developed. At the framework of macroscopic quantum theory conducted a joint decision of the Schrödinger and Poisson equations for the macroscopic wave function of the electrons and positrons. Resonance effects in the quantum exchange interaction leads to selforganization of the active volume of a charged medium, and continue up to dynamic compensation of the Coulomb field and the establishment of an electron-positron mode. The calculation results of the potential distribution and the wave functions of the exchange interaction are present.
