Abstract

In this paper, a new alternating direction implicit finite difference time domain (ADI-FDTD) method has been presented. The method relies on a more stable formulation of the perfectly matched layer (PML) absorbing boundary condition making it suitable for the simulation of photonic crystals (PhCs) based devices. Its accuracy and efficiency are demonstrated by numerical examples which are shown to be in excellent agreement with those reported in literature.
