1. An electromagnetic wave propagation disruption device with a metamaterial structure, comprising:

  • a plurality of conductive elements separated from each other and arranged on a top face of a substrate;

    a plurality of interconnection networks electrically interconnecting at least some of said conductive elements,wherein the interconnection networks are not electrically connected to each other, andwherein at least two of said interconnection networks are dimensioned differently to each other, such that distances between interconnected conductive elements are different from one interconnection network to another interconnection network of said at least two of said interconnection networks, to generate phase shifts between the conductive elements interconnected thereby, different from one of said interconnection networks to said another interconnection network;

    a ground plane positioned on a bottom face of the substrate with holes formed in the ground plane; and

    a set of metallic vias formed in the substrate and passing through an entire thickness thereof, each of said metallic vias comprising an upper end in contact with one of the conductive elements and a lower end arranged facing one of the holes formed in the ground plane, with no electrical contact with the ground plane but with an electrical contact with one of the interconnection networks.
