Abstract
We present a simple design to achieve bianisotropy at visible wavelengths: an ultrathin
plasmonic grating made of a gold grating covered by a thin flat layer of gold.
We show experimentally and through simulations that the grating exhibits magnetoelectric
coupling and features asymmetric reflection and absorption, all that with a
device thickness of a tenth of the operating wavelength. We compared the spectral
results and retrieved the effective material parameters of different polarizations and
devices. We show that both asymmetry and strong coupling between the incoming
light and the optically interacting surfaces are required for obtaining asymmetric optical
behavior in metasurfaces
