Abstract
One of the main problems in computing the UTD surface diffracted fields on surfaces described by Non-Uniform Rational B-splines (NURBS) is due to the difficulty in determining the geodesic paths the electromagnetic waves takes along the surface. In this paper we discuss some of the numerical algorithms that are used for computing surface diffraction on NURBS surfaces.
