The extraordinary electromagnetic response of nanostructured material, usually made up of a metallic structures distributed in within a dielectric matrix has attracted a lot of interest in recent years. These materials are technically called metamaterial (MM) since they possess different properties from their constituent materials. Several applications of metamaterials have already been demonstrated ranging from super-resolution imaging, invisibility cloaking. Our study seeks to explore the ultrafast response of MM which will find applications in Optical switching and limiting, IR and Terahertz Spatial light modulation.
