Mathematical Model and Computational Algorithm for Calculating the Effective Electromagnetic Parameters of a Magnetic Nanocomposite

Mathematical models (taking into account the exchange and the boundary conditions) and a computational algorithm for calculating the components of the effective permeability tensor and the effective permittivity of magnetic nanocomposites have been constructed. The results of calculating the effective permeability tensor for a magnetic nanocomposite based on an opal matrix using a model that takes into account the exchange and magnetic-dipole interactions between magnetic nanoparticles are presented.
