Abstract

Meta–surfaces or 2D metamaterials are generally considered in the far-field. Because of their resonant properties, they possess also an interesting band structure in the near-field. A meta–surface made of a set of parallel nano- wires deposited on a surface was studied. Bloch waves localized on the surface exist in the vicinity of the anti-resonances of the nano-wires. This band-structure leads to strong variations in the efficiencies of the meta- surface seen as a diffraction grating.
