Abstract
AbstractThis paper investigates a wire‐grid model for the scattering analysis of bodies using the method of moments (MoM). The accuracy of the model is explored in terms of basis functions, and the size and radius of the segments of the model are determined through a defined error function. The numerical simulations indicate that the wire‐grid model can accurately calculate the scattering problems when the proper model and the triangular basis function in the MoM are used. The optimal radius of the segments in the model is determined. However, the MoM with the sinusoidal basis function used in NEC2 results in very high error if both large size and large radius are adopted for the segments. © 2005 Wiley Periodicals, Inc.
