摘要

传统的迭代物理光学（IPO）方法基于Jacobi迭代方案更新表面电流，该方案通常对大型物体发散。为了控制IPO方法的收敛性，可以使用其他迭代方案，如高斯-塞德尔和逐次过松弛。在这项研究中，我们比较了五个散射体散射的三种迭代方案的收敛特性，这些散射体包括用阻抗材料建模的电完美或不完美导体。将IPO方法的精度与多级快速多极方法的精度进行了比较。

Comparison of Linear Iteration Schemes to Improve the Convergence of Iterative Physical Optics for an Impedance Scatterer

The conventional iterative physical optics (IPO) method updates the surface current based on the Jacobi iteration scheme, which typically diverges for large objects. To control the convergence property of the IPO method, other iteration schemes, such as Gauss–Seidel and successive over-relaxation, can be used. In this study, we compare the convergence properties of three iteration schemes for scatterings by five scatterers comprising electrically perfect or imperfect conductors modeled with an impedance material. The accuracy of the IPO method is compared with that of the multi-level fast multipole method.
