Optical Metamaterials and Metasurfaces
Metamaterials had enormous promise for realizing science fantasy and changing the world. The current demonstration of metamaterials is based on high-resolution nanofabrication, which requires costly processes and restricted resources. We are undertaking material research on low-loss hydrogenated amorphous silicon, printable nanoparticle embedded resin, and anodic aluminum oxide to overcome the constraints of conventional nanofabrication. We are also investigating multilayer deposition for experimental demonstration and hyperlens applications. Furthermore, we are doing cutting-edge bottom-up nanofabrication employing self-assembly, nanoparticles, block co-polymers, and other materials to apply metamaterials and plasmonics applications.Â
