%X An integral equation is derived from the electric field integral equation (EFIE) for plane wave illumination onto the metallic circular disc-ring structures by using Fourier transformation and separating the induced charge's contribution from the EFIE. For normal incidence, the equation is extremely simple and easy to be solved numerically regardless of the electric dimension of the structures. Comparison between RCS by this method and that by analytical solution for a disc shows the effectiveness of this approach. Numerical results are also given for the current distribution and the far radiation patterns of a disc-ring structure.
