摘要

与传统FDTD算法相比，高阶FDTD算法在计算精度和数值色散特性方面具有更大的优势。本文提出的高阶时域有限差分算法利用时域中心差分和空域四阶中心差分对传统时域有限差分算法进行了改进。通过实例验证了高阶时域有限差分算法的正确性。

Research and Application of High Order FDTD Algorithm

Compared with traditional FDTD algorithm, higher-order FDTD algorithm has more advantages in computational accuracy and numerical dispersion characteristics. The high-order FDTD algorithm proposed in this paper uses central difference in time domain and fourth-order central difference in space domain to improve the traditional FDTD algorithm. Several examples are used to verify the correctness of the high-order FDTD algorithm.
