Abstract
A diffractive device for fitting to a façade 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 including a plurality of tubular resonant elements arranged on the façade of the building, where the resonant elements are arranged in a substantially parallel manner on the façade of the 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 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.
