Abstract:
1. A waveguide ( 10 ) on which an electromagnetic wave impinges, said electromagnetic wave having a wavelength λ included in a given interval Δλ of interest centered on a λ centr , said waveguide comprising: a film defining a surface on a plane (X,Y) on which said electromagnetic waves are apt to impinge, and having a thickness in a direction (Z) substantially perpendicular to said surface, said film being realized in a material having a first refractive index (n a plurality of scatterers ( wherein the wavelength of the incident electromagnetic waves is comprised between and wherein the area (A scatt ) of the cross section of said scatterers is comprised between π·(Φ ref /6) 2 ≦A scatt ≦π·Φ ref 2 , where
