Summary:
Active frequency selective surface (FSS) structure is a kind of electromagnetic spatial filter, which has been widely used in the communication and radar systems. The spectralelement time domain method has been used to analyze the scattering characteristic of finite planar FSS structures. 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 absorbed boundary condition is employed to truncate the boundary. Numerical results demonstrate the accuracy of the method.
