Paper Abstract

We present a numerical algorithm for extracting all 36 linear constitutive parameters of a metamaterial crystal as a function of frequency and wavenumber based on driving a metamaterial with electric and magnetic charge and current. We demonstrate how spatial dispersion can result in bianisotropy in a centrosymmetric crystal. Several tests are performed on a 2D metamaterial crystal to validate these "current driven" constitutive parameters. Finally, we show how our method can be used to study spatial dispersion by studying constitutive parameters for small k.
