On well-posedness of some homogenized Drude-Born-Fedorov systems on a bounded domain and applications to metamaterials
The paper deals with a generalized Drude-Born-Fedorov system describing the propagation of electromagnetic waves in chiral materials, where the electric and magnetic fields are assumed to be coupled with the help of the chirality parameter. The generalization is related to the possibility to allow the material parameter, permittivity and permeability, to be not positive definite, as it happens for the so-called metamaterials. An existence and uniqueness result for such system is established under certain assumptions and applications to two models, dielectric-chiral photonic crystals and perfectly matching layers, are presented.
