Undistorted Transmission of a Useful Signal by Surface Spin Waves in a Metal–Ferrite–Dielectric–Metal Structure

Bulletin of the Russian Academy of Sciences Physics (2022)

Edwin H. Lokk S. V. Gerus A. Yu. Annenkov A. V. Lugovskoĭ

Abstract A study is performed of the characteristics of a surface spin wave propagating perpendicular to the direction of a uniform magnetic field in a tangentially magnetized plane-parallel metal–ferrite–dielectric–metal structure. It is established that at certain parameters of the structure, quasilinear portions appear in the dispersion dependence of this wave which can ensure the undistorted transmission of a useful signal modulating the surface spin wave.

Electron-phonon properties, structural stability, and superconductivity of doped antimonene

Physical review. B./Physical review. B (2019)

A. V. Lugovskoĭ M. I. Katsnelson А. Н. Руденко

Antimonene is a recently discovered two-dimensional semiconductor with exceptional environmental stability, high carrier mobility, and strong spin-orbit interactions. In combination with an electric field, the latter provides an additional degree of control over the material's properties because of induced spin splitting. Here, we report on a computational study of electron-phonon coupling and superconductivity in $n$- and $p$-doped antimonene, where we pay special attention on the effect of the perpendicular electric field. The range of accessible hole concentrations is significantly limited by the dynamical instability, associated with strong Fermi-surface nesting. At the same time, we find that in the case of electron-doping antimonene remains stable and can be turned into a state with strong electron-phonon coupling, with the mass enhancement factor $\ensuremath{\lambda}$ of up to 2.3 at realistic charge carrier concentrations. In this regime, antimonene is expected to be a superconductor with the critical temperature of $\ensuremath{\approx}16$ K. Application of bias voltage leads to a considerable modification of the electronic structure, affecting the electron-phonon coupling in antimonene. While these effects are less obvious in the case of electron-doping, the field effect in hole-doped antimonene results in a considerable variation of the critical temperature, depending on bias voltage.

Use of Multiband Acousto-optic Filters for Spectrally Encoded Signals Generation in Incoherent Optical Communication Systems

Abstract New acousto-optical (AO) coder of spectrally optical signals for optical code division multiple access systems (O-CDMA) was proposed and investigated. The coder was developed on a base of multi-frequency acousto-optical filter (MAOF). Control RF signals for MAOF were synthesized taking into account intermodulation distortions and interferences between different carrier frequencies incoming to MAOF. An industrial LED was used under system investigation.
