本文提出了一种利用 Calderon 恒等式预处理电场积分方程 (EFIE) 的新技术。与所有以前的 Calderon 预条件子相比，所提出的预条件子本质上是纯粹的乘法，适用于开放和封闭结构，易于实现，并且易于与现有矩量法 (MoM) 代码接口。数值结果表明，使用所提出的预处理获得的 MoM EFIE 系统能够快速收敛，与离散化密度无关。
In this paper, a new technique for preconditioning electric field integral equations (EFIEs) by leveraging Calderon identities is presented. In contrast to all previous Calderon preconditioners, the proposed preconditioner is purely multiplicative in nature, applicable to open and closed structures, straightforward to implement, and easily interfaced with existing method of moments (MoM) code. Numerical results demonstrate that the MoM EFIE system obtained using the proposed preconditioning converges rapidly, independently of the discretization density.
