摘要：
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. (C) 1999 John Wiley & Sons, Inc.
