Graphene – a material that has just recently been integrated with metamaterials, plasmonic nanoanteannas, waveguides, and photonic crystals - is establishing itself as a versatile and dynamic platform for realizing electrically tunable devices in hybrid nanophotonics and optoelectronics due to its excellent electrical and optical properties. In contrast to a single-layer graphene (SLG) sheet, nanopatterned graphene structures are shown to support highly confined surface plasmon modes that can be electrically tuned and have incredible potential for spatial and temporal light modulation in the mid-infrared range. In this presentation, we guide you through the essential steps of how to simulate such devices using the full potential of COMSOL Multiphysics®, first by starting with the basics of SLG modeling, and then by including approaches to multivariate modeling of the SLG sheets and nanostructured graphene in time and frequency domains.
