中文摘要：

近年来,基于帕德（Padé）近似法,一种面向一般Cole-Cole色散媒质的时域有限差分（FDTD）方案被提出.为了应用该方案处理实际的电磁问题,发展了一种对应的卷积完全匹配层（CPML）吸收边界.该吸收边界具有复杂度低的优势,便于问题空间和吸收边界的统一处理.通过一维、三维2个算例,初步证实了该边界的良好吸收效果.

英文摘要：

Based on the Padéapproximant method,a finite-difference time-domain（FDTD）scheme for general Cole-Cole media was presented.To apply this scheme to solve real-world electromagnetic（EM）problems,a corresponding absorbing boundary,convolutional perfectly matched layer（CPML）,is developed in this paper.The presented CPML possesses low complexity such that the FDTD scheme for problem space and ABC could be implemented simultaneously.Its high absorption efficiency is preliminarily validated by one-dimensional（1D）and three-dimensional（3D）examples.
