Graphene Metamaterials and Plasmonics from Terahertz to Optical Frequencies

There has been quite some interest in graphene metamaterials and plasmonics in the past few years. In this contribution, we will review graphene metamaterials and plasmonics in the terahertz, mid-infrared and optical domains. We will draw conclusions regarding the feasibility and advantages of graphene in each of these frequency domains. In particular, we will highlight the ease of changing the Fermi level in graphene, which may lead to a new generation of tunable metamaterials and plasmonics technology.
