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

Abstract

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.

期刊介绍： Technical Physics is a journal that contains practical information on all aspects of applied physics, especially instrumentation and measurement techniques. Particular emphasis is put on plasma physics and related fields such as studies of charged particles in electromagnetic fields, synchrotron radiation, electron and ion beams, gas lasers and discharges. Other journal topics are the properties of condensed matter, including semiconductors, superconductors, gases, liquids, and different materials.
