Abstract

In 1983 Rohklin [9] introduced the notion of multipole expansion for the rapid solution of first and second kind Fredholm equations arising from potential theory. Recently, these ideas have been extended to 3D by the work of White, Korsmeyer [7], and others interested in rapid parameter extraction for characterization of electrical circuits. At the same time, the Galerkin formulation of the boundary element method has recently received renewed attention. The Galerkin BEM ap- proach can substantially increase accuracy near corner singularities, while at the same time introduce desirable convergence pro
