A perfectly matched layer for subcell FDTD and applications to the modeling of graphene structures
This letter presents a perfectly matched layer (PML) for the subcell finite-difference time-
domain (FDTD) method for thin dispersive layers. Such a PML is useful when thin layers
extend to the boundaries of the computational domain. Emphasis is given on the case of
graphene thin layers, whose modeling with conventional FDTD produces significant
computational cost. The proposed formulation is accompanied by detailed validation and
error analysis studies.
