摘要

提出了一种求解瞬变电磁散射问题的谱元时域方法。它具有光谱精度高和块对角质量矩阵的优点。该方法基于高斯-洛巴托-勒让德多项式，采用伽辽金方法进行空间离散化。在无界问题中，采用完美匹配层截断边界。最后对主动频率选择曲面进行了分析，数值结果验证了该方法的准确性。

Analysis of transient electromagnetic scattering using spectral-element time-domain method

A spectral-element time-domain method is presented to solve the problems of transient electromagnetic scattering. It has the advantages of spectral accuracy and block-diagonal mass matrix. This technique is based on Gauss-Lobatto-Legendre polynomials and Galerkin's method is used for spatial discretization. The perfectly matched layer is employed to truncate the boundary in unbounded problems. Active Frequency selective surface is analyzed in the last part and numerical results demonstrate the accuracy of the method.
