16.1  Introduction

Boundary integral equation methods (BIEMs) are widely used for computation of three-dimensional (3D) electric fields [12,3,4,5,6,7,8,9,10,11]. They offer abilities to solve problems in unbounded regions and an easier method of building surface mesh than volume mesh, as needed when finite element method is employed for solving 3D problems.
