Abstract (en)
[origin: WO2014072431A1] A dihedral shaped device (10) is provided comprising two plates (l1a, 11b) forming between them an angle of π-2α, where 0<α<π/4. Each plate comprises a ground plane (12a, 12b), at least one dielectric layer (13a, 13b) and a network of radiating elements (14a, 14b). An incident wave is reflected by the device by virtue of a double reflection from both plates. The network of radiating elements of each plate allows a phase shift to be generated, from the exterior towards the centre of the dihedron, along an axis perpendicular to an axis of intersection of the two plates, according to a set phase law, allowing a deviation to be introduced relative to a specular reflection for a given operating frequency.
