Abstract

The novel singularity cancellation technique proposed by Khayat and Wilton has been adapted for computing the potential integrals involving the 3D Green\´s function and the linearly phased Rao-Wilton-Glisson (LP-RWG) basis functions. The proposed procedure is valid for singularities and "near"-singularities on arbitrarily-shaped triangular meshes, thus extending the reliability of the solutions obtained with this basis functions to well-shaped as well as ill-shaped triangles.
