Abstract

We present a bianisotropic retrieval method that assigns macroscopic electromagnetic properties of an array of nanostructured plasmonic elements (e.g. V-shape antennas) to a thin metasurface of equivalent bianisotropic tiles. A Finite Difference Frequency Domain (FDFD) solver is developed to integrate the bianisotropic descriptions and perform a full-wave simulation of the optical response of arrays of these tiles which are able to direct light to an arbitrary direction. The presented method is able to significantly reduce the computation load, since the detailed structures of the individual antennas are replaced by the effective bianisotropic properties.
