A Hybrid Method for Scattering from Conductor Objects

A hybrid method is implemented for calculating the electromagnetic scattering from three-dimensional, perfect electric conductor objects. The method consists of a hybrid method of moments (MoM)-physical optics (PO) without considering the coupling between the MoM and PO regions. The conjugate gradient method (CG) is adopted to solve the integral equation. The proposed hybrid method is validated combined with the results from the commercial software. Numerical results indicate that the proposed method has high accuracy.
