ABSTRACT:
Ad device substantially transparent to electromagnetic radiation of a certain frequency band is presented. The device comprises at least one dielectric structure of a predetermined thickness defined by the central frequency of the operational frequency band of the device, and comprises a predetermined substantially periodic inner pattern inside the dielectric structure composed of a two-dimensional array of substantially identical sub-resonant capacitive elements made of an electrically conducting material and capable of scattering said electromagnetic radiation arranged in a disconnected from each other spaced-apart relationship.
