In this project, we were concerned primarily with studying the physical phenomena, devices and designs related to negative refraction in the optical frequency range. We used theoretical work, computer simulations, and experimental studies to further the understanding of negative refraction in the high sought-after optical range. Our work has brought a number of significant advances, including experimental demonstrations of negative refraction well into the visible range to advanced designs in hyperlens and cloaking devices. The physics and repercussions of negative refraction in nonlinear optical systems has also been considered in our work, with the goal of understanding this newly opened and extremely exciting field of optics research.
