摘要：
An unsplit-field and efficient algorithm to implement the stretched coordinate perfectly matched layer (SC-PML) is proposed for truncating the finite-difference time-domain lattices. The main advantage of the proposed algorithm is that only one auxiliary variable is required in all corners and some edges of the PML regions by means of direct discretizing the second-order differential equation and a memory-minimized algorithm. Two numerical tests have been provided to validate the proposed algorithm.
