Abstract

In different types of problems, the Boundary Integral Equation (BIE) formulation involves domain integrals in which neither the field variables nor their derivatives are present. In those eases, it is desirable to find a convenient way to compute the domain integrals in such a fashion that is not necessary to introduce integration cells inside the domain. Several methods have been proposed to accomplish this goal and among the most relevant ones are the following: Analytical integration, the use of Fourier expansions, the Galerkin vector tech
