In this paper we present a numerical implementation of the Decoupled Potential Integral Equation (DPIE) based on a high order locally corrected Nyström method. The DPIE formulation allows to describing the scattering electromagnetic field by a perfect electric conductor in a decoupled way. The scattered scalar potential φscat is obtained entirely from the incoming scalar potential φin, and the scattered...
In this paper we present a numerical implementation of the Decoupled Potential Integral Equation DPIE. The DPIE formulation allows to describe the scattered electromagnetic field by solving a boundary value problem for the vector and scalar potentials Ascat and øscat separately. The formulation allows to obtain the exact scattered electric and magnetic fields for any frequency ω ≥ 0. The formulation...
A high-order Nyström scheme is developed for electromagnetic (EM) scattering problems of smooth objects. The implementation is based on different well-known charge-current formulations. This study aims to develop a novel quadrature scheme to compute different singular integrals that appear on integral equation methods in EMs. The proposed quadrature scheme is used on a locally corrected Nyström method,...
