Abstract :
This paper introduces a perfectly matched layer (PML) for the 2-D unconditionally stable finite difference time domain (US-FDTD) method by making use of an approximate Crank-Nicolson scheme. The 2-D US-FDTD with this new PML preserves the property of unconditional stability (US) and thus allows utilization of larger time steps, which can result in substantial reductions in computational time for open boundary problems
