Abstract
An electromagnetic wave propagation disruption device with a metamaterial structure including: a plurality of conductive elements arranged on a top face of a substrate; a plurality of interconnection networks electrically interconnecting at least some of these conductive elements, wherein these networks are not electrically connected to each other. At least two of these networks are dimensioned differently to each other, thus involving that distances between interconnected conductive elements are different from one network to another, to generate phase shifts, between the conductive elements interconnected thereby, different from one network to the other. A ground plane with holes is arranged on a bottom face of the substrate and metallic vias are formed in the substrate, each of them including an upper end in contact with a conductive elements and a lower end arranged facing one of the holes of the ground plane, with no electrical contact with the ground plane.
