摘要

本文利用改进的隐式-显式时域有限差分(HIE-FDTD)混合方法，提出了一种高效的有损媒体实现方法。我们为建议的实施制订了不同的方案，包括向前-向后的方案。数值结果验证了该格式的有效性，并与高效的交替方向隐式时域有限差分法和传统时域有限差分法进行了比较。

Efficient Implementation of Lossy Media using Improved 3-D HIE-FDTD Method

This paper presents an efficient lossy media implementation using the improved hybrid implicit–explicit finite-difference time-domain (HIE-FDTD) method. Various schemes, including a forward-backward scheme, are formulated for the proposed implementation. The efficiency of formulated schemes are validated through numerical results and compared to the efficient alternating-direction-implicit (ADI)-FDTD and the conventional FDTD methods.
