The Principle of Symmetry of Kinetic Coefficients for Media with Ferrite Inclusions and its Application to Nonreciprocal Bi-Anisotropic Composites

摘要

The principle of the symmetry of kinetic coefficients (the Onsager-Casimir principle) is formulated for bi-anisotropic media containing dissipative ferrite inclusions and metal strip elements. Electrodynamic description of bi-anisotropic particles on the base of strip-line-coupled magnetostatic wave resonators is developed and analytical closed-form expressions for the tensor polarizabilities are obtained for an arbitrary direction of the bias magnetic field and an arbitrary resonator shape. The results open a pos- sibility to theoretically predict properties of novel nonreciprocal electrically controllable bi-anisotropic composites with exotic electromagnetic properties.
