The accurate and fully 3-D analysis of graphene surface conductivity models by means of a frequency-dependent finite-difference time-domain method is introduced in this paper. For the infinite sheet to be consistently simulated, the novel technique uses a set of periodic boundary conditions that lead to a unit cell excited with a spectral scheme in terms of(More)
An efficient 3-D FDTD formulation for the precise analysis of electromagnetic phenomena in graphene structures is presented in this paper. The new concept considers the surface nature of graphene's conductivity and encompasses it directly into the integral form of Maxwell's equations, avoiding the necessity to discretize the material's transverse dimension(More)
An efficient finite-difference time-domain methodology combined with a robust subcell formulation for the precise analysis of infinite graphene sheets is introduced in this paper. The graphene surface conductivity is modeled through a volume conductivity profile, with the pertinent periodic boundary conditions applied to the unit cell's lateral surfaces.(More)
Graphene is a newly fabricated 2-D material that has attracted much interest due to its potential electronic applications. In this paper, a fully 3-D FDTD-based scheme is proposed for the simulation of electromagnetic interactions with graphene sheets. Graphene's 2-D character is accounted for by a subcell technique, while its dispersive nature is treated(More)
