Abstract :
In this paper we present a simple and efficient, fully numerical technique for the evaluation of 4-D reaction integrals in the Method of Moments. The proposed approach is applied to the magnetic field integral equation (MFIE), where the gradient of the Helmholtz potential is present in the source integral; this case is more demanding than the electric field integral equation (EFIE) case. However, the analogous approach can be applied also to weakly singular and near singular integrals.
