摘要

本文将ADI-FDTD算法应用于三维物体的散射模拟。讨论了入射平面波的引入、全场区与散射场区之间的连接边界条件以及近场到远场的变换等关键技术。数值结果表明，在相同精度下，ADI-FDTD算法的计算时间仅为传统FDTD方法的1/6。

ADI-FDTD algorithm for three-dimensional scattering analysis

In this paper, the ADI-FDTD algorithm is applied to simulate scattering of three-dimensional objects. A few key techniques include the introduction of an incident plane wave, connective boundary condition between total-field zone and scattering-field zone and near-to-far field transformation are discussed. It is shown from the numerical result that the computation time of the ADI-FDTD algorithm is only 1/6 that of the conventional FDTD method with the same accuracy.
