A method is proposed for modeling the complex dielectric constant of an anisotropic hierarchically constructed nanocomposite with a periodic structure, based on the complex application of quantum mechanical calculations, an effective medium model, and equivalent equivalent circuits. The dielectric constant of the TiO2 - Al2O3 nanocomposite under the action of external high-frequency electromagnetic radiation has been investigated. The wavelength ranges at which resonance bursts are observed are determined. The possibility of controlling the maxima of difference losses and resonance absorption maxima by changing the geometric parameters of the nanocomposite is shown.
