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.
