A numerically efficient summation technique, using the FFT algorithm, for the calculation of the impedance matrix in the method of moment solution to electromagnetic problems associated with planar periodic structures is presented. Comparisons between the CPU times for the conventional brute‐force summation and the present technique are given. Copyright © 1988 Wiley Periodicals, Inc., A Wiley Company
