Abstract :
A split field perfectly matched layer (PML) is implemented for the (2-D) two-dimensional and three-dimensional (3-D) unconditionally stable Crank-Nicolson finite difference time-domain analysis (CN-FDTD) methods. It is shown that the CN-FDTD method remains stable with the PML media. The effectiveness of the PML in CN-FDTD method is demonstrated through numerical examples.
