The object of research: structured nanocomposites with a filler in the form of beads with a conductive coating that form a segregated structure, molecular composite materials with a phase transition based on vanadium dioxide, an acousto-optical cell based on TeO2 crystals. Nonlinear optical process of forced Raman scattering (SRR) in single-mode quartz fibers. Subject of research: electrodynamic characteristics of materials, in particular nonlinear parameters of optical fibers as active materials for optical amplification and generation of terahertz radiation. The purpose of the work: search and research of materials for protective, absorbing screens from electromagnetic radiation with a minimum reflection coefficient, search for materials to control the characteristics of electromagnetic radiation, modeling of the propagation of acoustic waves in the anisotropic medium of acousto-optical cells based on TeO2 crystals. Determination of the main fundamental physical processes and mechanisms that take place during the interaction of electromagnetic fields with structured nanocomposites, including the study of the fundamental features of Stokes SRS amplification Research methods: ultra-high-frequency waveguide methods and numerical methods for calculating the main electrodynamic and acoustic characteristics. For the first time in the microwave range, structured nanocomposites with a filler in the form of balls with different conductive coating, which form a segregated structure and molecular composites with a phase transition based on vanadium dioxide, were investigated. The temperature spectra of the specified materials were studied, the attenuation and reflection coefficients of the electromagnetic wave were determined, recommendations were developed to improve the efficiency of the interaction of materials with microwave radiation Product Description popup.authors Zagorodniy Volodymyr V.
