A Hybrid Method Based on ADI-FDTD and Its Celerity Algorithm

该文介绍了FDTD与ADI-FDTD相结合的方法,提出了减小因两种不同计算方法在边界引起反射的加权平均的方法,并给出了ADI-FDTD计算线性、无耗、各向同性媒质的快速算法。计算结果表明了该方法的有效性。

The paper presents a hybrid method based on FDTD and ADI-FDTD, introduces a method of weighted average to reduce the reflection caused by two different methods on the boundary, and presents a celerity method for the linear, lossless and isotropic medium. The simulation shows that the method is feasible.
