N2 - A set of integral equations based on the surface/surface formulation have been developed in this paper for analyzing the electromagnetic scattering by one-dimensional periodic structures. To compare the accuracy, efficiency, and robustness of the formulation, the electric field integral equation (EFIE), magnetic field integral equation (MFIE), and combined field integral equation (CFIE) have been developed to analyze the same structure for different excitations. Due to the periodicity of the structure, the integral equations have been formulated in the spectral domain using the Fourier transform of the integrodifferential operators. The generalized biconjugate gradient-fast Fourier transform (BiCG-FFT) method with subdomain basis functions has been applied to solve the matrix equation.
