Abstract
This paper is devoted to the Non-Uniform Rational B-Spline Isogeometric analysis of the On-Surface Radiation Condition (OSRC) method for solving two- and three-dimensional time-harmonic acoustic scattering problems. In addition, a Reduction of the OSRC formulation based on a plane wave ansatz is introduced. This development enhances the efficiency of the OSRC methods which has been demonstrated by studying a few two- and three-dimensional examples.
