摘要：

This paper presents an alternative procedure for the evaluation of the physical optics (PO) contribution into a hybrid moment method-physical optics (MM-PO) code. The proposed formulation includes a linear interpolation of the phase over large triangular subdomains for the PO regions, where the radiated field can be analytically determined. This allows a drastic reduction of the computational cost, while maintaining or even improving the degree of accuracy. In this way, the scope of application of the MM-PO hybrid code is enhanced to larger problems in terms of wavelength. (C) 2001 John Wiley & Sons, Inc.
