Resumen:
In recent papers, it has been theoretically shown that by using dual-period wire gratings it is possible to control the relative eciencies of the di racted orders, regardless of wires´ material, incident polarization and the wavelength. In this paper we experimentally demonstrate, for the rst time, that by appropriately choosing the geometrical parameters of a nanometric periodic structure, it is possible to control the optical response in the visible range. We show examples of nanostructures designed to cancel out or to intensify a particular di raction order. Such nanostructures allow a broad control over the directionality and the intensity of the di racted light, which makes them useful for applications such as highly directional optical nanoantennas and photonic multiplexers.
