Our research seeks to develop new artificial microscale and nanoscale materials (metamaterials) with unusual electromagnetic properties such as a negative index of refraction. Currently we are placing particular emphasis on harnessing and further developing the groundbreaking theory of transformation electromagnetics which prescribes metamaterials that allow controlling the spatial distribution of electromagnetic fields almost at will. Using this approach we are designing enabling microwave/optical structures and components for a range of applications including telecommunications, super-resolution imaging, and invisibility cloaks.
