The aim of the project is to develop quasi-photon structures based on metamaterials with controlled magnetic and dielectric characteristics for their application as an element base in the development of microwave equipment, mobile communications, the Internet, digital data networks, where it is necessary to increase both the transmission speed and the There are arrays of information. Methods of investigation - the rare-phase method of obtaining composites with a homogeneous distribution of the filler with the previous ultrasonic dispersion; the method of scanning electron and optical microscopy for the study of structural features of composites; Conductometric method for determining the conductivity of DC composites; study of electromagnetic characteristics of photonic structures, using the vector analyzer of Agilent PNA network analyzer, frequency range of measurement from 10 MHz to 67 GHz; Brahovskikh impedance method for the calculation of electrodynamic characteristics by the Monte Carlo method for simulation of percolation processes in composites. A complex study of processes and methods for the formation of quasiphotonic structures in conjunction with experimental and theoretical studies of the influence of the concentration and type of filler (carbon nanotubes, graphite nanoplastics, barium hexaferite powder), frequency range of electromagnetic radiation, temperature on their electrical and electrodynamic properties was carried out. The theoretical model of calculations of spectra of reflection and passing of electromagnetic radiation (frequency range 3-50 GHz) 1D periodic photonic structures in the form of a plane boundless screen and for 1D photonic structures which allowed to determine influence on the positions, shape, width, depth and number of forbidden zones of parameters of layers types and, from which the photonic structure is formed.
