摘要：
A new method to solve the electromagnetic scattering problem of finite periodic structures is proposed in this paper. The surface current of periodic structural unit is modeled by specific entire domain basis function to reduce the unknown. The electric field integral equation (EFIE) can be solved by method of moments (MoM), and the block Toeplitz characteristic of the impedance matrix makes matrix vector multiplication to be accelerate by the conjugate gradient fast Fourier transform (CG-FFT). The tedious and time-consuming procedure of the subdomain basis function in solving large-scale periodic structural problems is avoided.
