Summary: The objective of this project is to discover ways to minimize optical losses in plasmonic and meta-material nano-antennas. Nano-antennas are exciting new components that can be used in refractometric sensors, meta-material lenses, plasmonic circuitry, spectrally-selective coatings and filters, or single molecule biosensors. However, exploitation of the field is being held back by the intrinsic chemical and physical limitations of the various materials available. In particular, improvements in the corrosion resistance and the electrical conductivity at optical frequencies are needed. This project will consequently enhance prospects for technological breakthroughs in this field.
