A numerical technique is described for solving the problem of electromagnetic scattering from perfectly conducting bodies. The approach is illustrated by considering the two-dimensional problem of TM scattering from perfect electric conducting cylinders. The problem is formulated as a matrix equation involving the fourier coefficients of the far-field pattern as unknowns. and an analytic continuation procedure is used to extend the far-field representation into the near field in order to apply boundary conditions. The calculated far-field pattern for plane wave scattering from a square cylinder is given as an example. Copyright © 1969 by The Institute of Electrical and Electronics Engineers, Inc.
