Detailed Description
The invention consists of extremely anisotropic metamaterials which are broadband for negative refraction applications. The metamaterials have simple structures and are easily fabricated using either top-down lithography or bottom-up self-assembly methods. They represent the first metamaterials for negative refraction applications in the ultraviolet.
The metamaterials market is early-stage, emerging, and rapidly growing. Research on negative refraction and metamaterials has exploded over the past six years. Metamaterials in the microwave and radio frequency range are very likely to be commercialized in the near future. Early civilian applications of metamaterials are found in miniature antennas in the radio frequency range. In the long-term, negative index metamaterials will find applications in a variety of optical and electronic devices, permitting for decreases in device size and power.
