Abstract
A device for forming at least one focused beam in a near-field zone, from an electromagnetic wave incident on the device, is remarkable in that it comprises at least one layer of dielectric material comprising at least partially at least one cavity, the at least one cavity being filled in with a medium having a refractive index lower than that of the dielectric material. The at least one cavity is targeted to be cylindrical or cone-shaped and comprises at least one base surface, defined with respect to an arrival direction of the electromagnetic wave, and at least one lateral surface. The at least one base surface is delineated by a base edge line which has a shape of a crescent moon, comprising a concave base edge line segment and a convex base edge line segment, which shape, and/or orientation and/or associated base angles between the at least one base surface and the at least one lateral surface control an angular position of a projection of the at least one focused beam on a plane orthogonal to the arrival direction of the electromagnetic wave and comprising at least part of the at least one base surface, called an azimuth angle.
