This project will focus on a goal of engineering novel plasmonic metamaterials for manipulating light at the nanoscale. In particular, it will employ curved anodized alumina templates as well as 3D hybrid structures to explore light bending and strong resonances at the visible spectral range. Plasmonic metamaterials offer a unique ability to control subwavelength light propagation, for achieving unprecedented sensing sensitivities and emerging nanophotonics phenomena.
