Abstract :
We introduce and compare two split-field implementations of the perfectly matched layer (PML) for the unconditionally stable locally one-dimensional (LOD) finite-difference time-domain (FDTD) method. The LOD-FDTD formalism is expanded in terms of a symmetric source implementation. It is verified that the relative performance of both PML implementations is superior to the split PML performance in the alternating direction implicit (ADI) FDTD method
