 Title: Method of Moments (MoM): Application for Solving Augmented Electric Field Integral Equation (AEFIE) Author(s): Li, Binye Contributor(s): Chew, Weng Cho Subject(s): Computational Electromagnetics EFIE MoM Abstract: Surface integral equations (SIEs) are promising candidates for modeling circuits because they reduce degrees of freedom by restricting physical unknowns on the surface, which simplifies complex structures. However, there are still challenges related to achieving stability over a broad frequency band. Specifically, the low frequency breakdown of electrical field integral equation (EFIE) operator is discussed in this work. In order to solve or alleviate this problem, the separation of irrotational and solenoidal current must be accomplished. A proposed method, the Augmented Electrical Field Integral Equation (AEFIE), is intended to separate the current element by introducing charge as another variable and relate irrotational current and the charge vector. Finally, the method of moments (MoM) is applied to solve the integral equation by projecting the current onto RWG basis and performing subspace projections to fill out the integral equation operator matrix. For complicated circuit structure, MoM can be accelerated using the fast multipole algorithm (FMA).
