Object of study - kvazifotonna multilayer structure of the metamaterial elements created based composites Carbon Nanomaterials Carbon Nanomaterials and polymer-polymer. Purpose - development of scientific bases of creation kvazifotonnyh structures based on periodic multilayer elements using polymer-based nanocomposites nanocarbon wavelength and type dispersed in a matrix of major components. Setting influence the type and concentration of the carbon component in the polymer compositions dielectric constant, transmittance and reflectance kvazifotonnyh structures based on them. Methods-liquid phase method for composites with homogeneous distribution of filler to the previous ultrasonic dispersion; method and scanning electron microscopy to study the optical structural features composites; conductometric method for determining the electrical conductivity of composites DC; study the electromagnetic characteristics of photonic structures using radiation vector analyzer Agilent PNA, measurement frequency range from 10 MHz to 67 GHz; Brehovskyh impedance method for calculating the electromagnetic characteristics of a Monte Carlo simulation for composites in percolation processes. Vpliv investigated the type and concentration of carbon filler on the frequency dependence of the complex permeability diyelektrichnoyi in the frequency range 1-65Hhts. It was established that the composite material, the filler which forms a chain structure (L285 + HNP) is characterized by non-linear growth? '?' 'With increasing concentrations napovnyuvacha.Vыyavleno, the impact of dysterhovanisti CNT in epoxy matrix on the size and nature of the frequency dependence of the dielectric characteristics KM L285 / NTD. The modeling spectra of reflection and transmission of electromagnetic radiation (frequency range 3-50 GHz) 1Dperiodychnymy photonic structures (LH) ku form of a flat screen and unlimited for 1D photonic structures placed in a rectangular waveguide the influence of the position, shape, width, depth and number of banned zones types of settings layers L and H, which consists of photonic structure. Show that when the Bragg conditions (optical layer thicknesses are equal), there is a forbidden zone, the provisions of which corresponds to the average frequency of the investigated frequency range. Reducing the thickness of optical layer photonic structure of values ??leads to asymmetric forms gap, increasing its width and shift towards more high frequencies.
