Simulation of Graphene-based Materials and Devices for Sub-Terahertz Applications

The electromagnetic properties and behavior of nanomaterials and nanomaterial-based devices are simulated using analytical models and numerical methods. Graphene nanomaterials are the most explored, with several different proposed applications. To design a graphene-based device that meets specific functional requirements, reliable models that take into account the geometry of the device, in addition to the properties of graphene. In this way, simulation of the response based on variations in geometrical parameters is possible. Among the existing techniques, finite element method for field analysis and device compact modeling for circuit simulators are here referred. In this paper, our design approach is presented, which begins with metamaterial and device modeling based on experimental data fitting and progresses to sensitivity analysis conducted using a factorial design of numerical experiments.
