Assignee: KING'S COLLEGE LONDON
Field: Telecommunications (Electrical engineering)
Classification: CPC G  H  B | IPC G  H

Claim 0:
1. A plasmonic metamaterial structure comprising:
a plurality of optical antenna elements comprising:
a first electrode, a second electrode and a plasmonic nanostructure element located between the first electrode and the second electrode to form an electron tunnelling junction between the first electrode and the second electrode; and
the plurality of optical antenna elements positioned with respect to each other such that an electromagnetic field of a given optical antenna element spatially overlaps that of adjacent optical antenna elements and the adjacent optical antenna elements are electromagnetically coupled to allow the plurality of optical antenna elements to act as a plasmonic metamaterial and wherein at least one of the plurality of optical antenna elements comprises a target-sensitive material located in the electron tunnelling junction.
