From electronics to metatronics to graphene metamaterials

We discuss the concept of optical metatronics, i.e., metamaterial-inspired optical nanocircuitry, in which the metamaterials and plasmonic optics can bring together three fields of “electronics”, “photonics” and “magnetics” seamlessly under one umbrella - a paradigm which I call the “Unified Paradigm of Metatronics”. We present an over view of our most recent analytical, numerical and experimental results in developing the optical metatronics. We also show how this concept can be merged into the platform of graphene, which is one-atom-thick carbon layers, leading to the possibility of one-atom-thick infra-red metamaterials and transformation optics. Future directions in these topics will also be forecasted.
