Abstract
A metasurface device includes a ground structure able to have a ground plane function, the ground structure being able to be alternately in an insulating state, wherein it prevents the propagation of the surface wave over the front surface of a substrate so as to prevent the antenna element from radiating, and in a conductive state, wherein the ground structure has the ground plane function, allowing the propagation of the surface wave over the front surface of the substrate from the emission/reception device to the conductive patches, or vice versa, the ground structure being able to change from the insulating state to the conductive state through illumination of the ground structure at a wavelength called a switching wavelength.
