Electrodynamic characteristics estimation for aperiodic random composite media

Abstract

The paper presents approaches to electro-dynamic characteristics estimation for artificial composite media, among which a periodic random media are especially distinguished. Resonant circuit implementation based on thin-film ferromagnetic nanostructures is possible in a periodic composite media. Chiral media, photonic, magnonic crystals and layered structures are of particular interest. Approaches based on spin waves excitation are important for ferromagnetic nanostructure study. Propagation and scattering of electromagnetic waves in near-field and far-field regions of plane structure for layered structures in composite media can be described with Maxwell's equations in mag-netostatic approximation, electrodynamic and exchange boundary conditions, and Green's method of tensor functions.
