Abstract: A method is proposed for modeling the complex dielectric constant of an anisotropic hierarchically constructed nanocomposite with a periodic structure. The method is based on a complex application of quantum mechanical calculations, the effective medium model, and equivalent circuits. The dielectric constant of the TiO$_{2}$–Al$_{2}$O$_{3}$ nanocomposite under the impact of external high-frequency electromagnetic radiation has been investigated. The wavelength ranges are determined at which resonance bursts are observed. The possibility of controlling the maxima of difference losses and resonance absorption maxima by varying the geometrical parameters of the composite is shown.

Keywords: dielectric constant, nanocomposite, mathematical modeling, periodic structure.
