摘要: In this paper, for the first time, we derive appropriate form of Maxwell-Dirac equations simulation of the coupling transport electromagnetic fields and carriers in graphene nanostructures, propose a time splitting spectral method numerical solution multiphysics problem.In time splitting spectral method, split each step into three substeps. substep, linear nonlinear parts complicated system, then iteratively solving simple part by linearizing the part. The derivatives are discretized finite difference with second order accuracy schemes. spatial differential operators approximated differentiation matrices. proposed numerical is validated examples that simulate propagation wave in graphene nanowaveguides.
