Anti-reflecting lining structure with a diffraction grating using resonant elements
A diffractive device for fitting to a façade (11) of a building, or to any other reflective wall, exposed to electromagnetic radiation emitted by a source located at a distance from the building, the device comprising a plurality of tubular resonant elements (12) arranged on the façade of said building, characterised in that said resonant elements are arranged in a substantially parallel manner on the façade (11) of said building in such a way as to form a diffraction grating and are oriented in a substantially perpendicular direction to the plane defined by the propagation vectors of the incident and reflected electromagnetic waves, each resonant element (12) being configured to form an LC resonator capable of re-radiating a wave corresponding to the incident wave affected by a phase shift; the set of resonant elements being arranged in such a way that the incident wave is diffracted in a preferential direction. The diffraction grating formed in this way is advantageously not as thick as the existing devices. The overall structure is both lighter and less susceptible to deformation.
