The Incremental and Differential Maxwell Garnett Formalisms for Bianisotropic Composites

Abstract

Two approaches to homogenize bianisotropic particulate composite mediums are presented: (i) the Incremental Maxwell Garnett (IMG) formalism, in which the composite medium is built incrementally by adding the inclusions in N discrete steps to the host medium; and (ii) the Differential Maxwell Garnett (DMG) formalism, which is obtained from the IMG in the limit N right arrow infinity. Both formalisms are applicable to arbitrary inclusion concentration and are well-suited for computational purposes. Application of both formalisms is exemplified here by numerical results for a uniaxial dielectric composite medium and a chiroferrite.
