对柯尔－柯尔（Cole?Cole）色散媒质的时域有限差分（FDTD）方案尝试给出改进：（1）保留了Cole?Cole经验公式中的静态电导率项；（2）扩展到三维情形；（3）人体乳房组织的模型参数源于实验测量。数值算例结果初步证实改进方案的可行性和有效性。改进方案适用于模拟更一般柯尔－柯尔色散媒质中的电波传播。

For finite?difference time?domain ( FDTD ) scheme in simulation of electromagnetic wave propagation in Cole?Cole dispersive media. Several improvements are made:(1) preserving a term with static ionic conductivity in Cole?Cole model, which is fit for real Cole?Cole media; ( 2 ) extending to three?dimensional ( 3?D ) case; ( 3 ) selecting parameters of human breast tissues from experiment. Feasibility and validity of the scheme is preliminarily demonstrated by numerical examples. The modified scheme is propitious to wave propagation in general Cole?Cole dispersive media.
