Fast iterative analysis of two‐dimensional scattering by a large but finite array of perfectly conducting strips requires efficient evaluation of the electric field. We present a novel multigrid algorithm that carries out this task in CN computer operations, where C depends logarithmically on the desired accuracy in the field, and N is the number of spatial grid points. Numerical results are presented, and extensions of the algorithm are discussed. © 2002 Wiley Periodicals, Inc. Microwave Opt Technol Lett 32: 454–458, 2002.
