Polarization phenomena in periodic metasurfaces at oblique incidence

Kruk, Sergey; Poddubny, Alexander N.; Helgert, Christian; Decker, Manuel; Powell, David; Pertsch, Thomas; Neshev, Dragomir; Kivshar, Yuri


We study experimentally and theoretically oblique incidence polarization phenomena for periodic metasurfaces of different symmetries. We show that the strength of the optical activity, circular dichroism and asymmetric transmission is dependent on the rotational symmetry of the metasurface lattice. We verify the predictions of the analytical model by the experimental study of optical metasurfaces with 4-fold, 6-fold and 5-fold rotational symmetry and demonstrate an excellent agreement.
