1. A tuneable impedance structure comprising:

  • (a) a plurality of electrically conductive elongate wires, each conductive elongate wire being defined by a plurality of spirals, the spirals of each conductive elongate wire having a pitch and being spaced apart along a major axis of said conductive elongate wire; and

    (b) an arrangement for varying the pitch of the spirals of said plurality of conductive elongate wires to thereby tune the impedance of said tuneable impedance structure.
