title: Giant cross polarization in a nanoimprinted metamaterial combining a fishnet with its Babinet complement.
abstract: We present a large area (1 cm2) nanoimprinted metamaterial comprising a fishnet structure and its Babinet complement, which shows giant cross polarization. When illuminated with s-polarized light, the reflected beam can be p-polarized up to 96%, depending on the azimuthal orientation of the sample. This experimental result is close to the result of numerical simulations, which predict 98.7% of cross-polarization. It is further shown, that 95-100% cross polarization is only achieved in the case when the fishnet is combined with its Babinet complement. Each structure alone (either an ordinary fishnet or a plane with metallic rectangles only) shows substantially less polarization conversion.
