# Losses

In current negative-index optical metamaterials, the damping is too large for real-world applications. It is presently unclear how much this can be improved by modified designs and other choices of constitutive materials. This project will work to understand and reduce losses in metamaterials. (C. M. Soukoulis, Th. Koschny)
