Frequency‐domain plane‐wave scattering from a perfectly conducting two‐dimensional cylinder is analyzed by a hybrid formulation combining the method of moments (MoM) and physical optics. Asymptotic techniques are employed to evaluate many of the impedance matrix integrals. Comparisons are made with standard MoM solutions. A significant reduction in computer memory and run time is achieved. ©1999 John Wiley & Sons, Inc. Microwave Opt Technol Lett 21: 117–121, 1999.
