摘要
An efficient algorithm for modeling dispersive media in finite-difference time-domain methods is presented. It is based on the auxiliary differential equation method for treatment of Lorentz media with an arbitrary number of relaxations. The algorithm shows excellent accuracy of second order in time and space and is efficient in both memory requirements and computational effort. (C) 1997 Optical Society of America.
