Abstract:A delta gap source formulation suitable for use in locally corrected Nyström (LCN) discretizations of electric field integral equations is presented. The delta-gap is applied to an edge (or group of edges) between a set of faces. Due to the pointsampling used in the LCN method, the delta gap effect is distributed across the faces shared by the source edges. The LCN delta gap is validated using results from the moment method.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
