Modeling of nonreciprocal microwave devices based on magnetic nanocomposites

The rigorous mathematical models of magnetic nanocomposite-based nonreciprocal microwave devices are developed to solve the 3D diffraction boundary problems for the Maxwell`s equations with electrodynamic boundary conditions гsing the effective electromagnetic parameters of magnetic nanocomposites. The complex components of the effective permeability tensor of magnetic opal nanocomposite depending on the DC magnetic field were calculated using the electrodynamic model by the decomposition on autonomous blocks with magnetic nanoinclusions and virtual Floquet channels. Sing the numerical algorithm based on the projection method the results of electrodynamic calculation of scattering parameters of magnetic opal nanocomposite-based Y-circulator depending on the frequency were obtained.
