Coupled model for the study of effective parameters of ferroelectric metamaterials

We study the homogenized permittivity of ferroelectric-dielectric composites under a static electric field. A rigorous numerical model is used to take into account the coupling between the electrostatic problem and the electric field dependent permittivity of the ferroelectric material. We consider metamaterial structures in two dimensions and study their effective permittivity, losses, electrically induced anisotropy and tunability.
