This program explored novel approaches to overcome common limitations of infrared metamaterials in order to achieve lowelectromagnetic losses and broad tunability of the electromagnetic response. One direction of the proposed work was toimplementgraphene-based metamaterials. A complimentary direction of research was focused on the development and exploration of hybridmetamaterials with reconfigurable properties at the level of individual cells operating at infrared frequencies. The proposed hybridmetamaterial, combining split ring resonators with phase change materials, enabled convenient adjustments of the refraction indexprofile across the area of the metamaterial.
