Abstract

In this paper, an efficient auxiliary differential equation (ADE) method is proposed to implement stretched-coordinate perfectly matched layer (SC-PML) in finite-difference time-domain (FDTD). The derivation of discrete difference operators for the ADE-PML equation for FDTD is also presented. The numerical results show that the ADE-PML's absorbing effect is much better than Mur's second order ABC and RC-PML.
