Abstract
We review some recent developments on finite-difference time-domain (FDTD) techniques applied for large scale simulations, including: (1) The perfectly matched layer (PML) absorbing boundary condition and its extensions to various geometries and media, (2) dispersion-relation-preserving (DRP) schemes to reduce grid dispersion error, (3) subgridding techniques for structured FDTD grid refinement, and (4) unconditional stable schemes to overcome the Courant stability limit.
