The time-domain discrete Green's function method (GFM) characterizing the FDTD grid boundary.

For a given FDTD simulation space with an arbitrarily shaped boundary and an arbitrary exterior region, most existing absorbing boundary conditions become inapplicable. A Green's function method (GFM) is presented which accommodates arbitrarily shaped boundaries in close proximity to a scatteri...
