Abstract

This article focuses on the basic multilevel FMM algorithm as a way to quickly compute the field caused by a collection of Helmholtz source points at an arbitrary field point. To keep the description of the implementation simple, the authors assume that the field is desired at each source point, as would normally be the case when constructing an impedance matrix for a physical problem. Through this basic, but detailed, description, the authors hope to make the multilevel Helmholtz FMM more accessible for a variety of problems.
