Abstract Frequency‐domain plane‐wave scattering from perfectly conducting two‐dimensional strips is analyzed by a hybrid formulation combining the method of moments (MOM) and physical optics (PO). Asymptotic techniques are employed to evaluate many of the impedance matrix integrals. Comparisons are made with other MOM algorithms. A significant reduction in CPU time is achieved. © 1994 John Wiley & Sons, Inc.
