摘要

本文提出了一种求解时域电场积分方程(TD-EFIE)的新方法。所提出的方法将电路仿真中已知的与问题无关的拉普拉斯变换数值反演(NILT)概念发展为适合 TD-EFIE 求解的完整时间步进程序。该方法保留了 NILT 在高阶时间表示和数值稳定性方面的主要优点。更重要的是,NILT 不需要递归卷积,因为它完全基于 EFIE 拉普拉斯域形式的时刻法(MoM)求解。本文列举了几个实例来验证所提方法的准确性。

TD-EFIE Method-of-Moments Solution Using the Numerical Inversion of the Laplace Transform With Time-Stepping Re-Initialization
This article presents a new approach to solving the time-domain electric field integral equation (TD-EFIE). The proposed method develops the notion of problem-independent numerical inversion of the Laplace transform (NILT), which is known in circuit simulation, into a complete time-stepping procedure suitable for the solution of the TD-EFIE. The key advantages of NILT, in terms of the high-order temporal representation and numerical stability, are maintained in the proposed method. More importantly, NILT does not require recursive convolution due to its being entirely based on the method-of-moment (MoM) solution of the Laplace-domain form of the EFIE. Several examples are presented to validate the accuracy of the proposed method.
