When the Partition of Unity Method is applied to a discretised integral equation form of the Helmholtz operator, the computational cost is dominated by the evaluation of highly oscillatory integrals over discretisations. This paper presents a new num... Read More about A numerical coordinate transformation for efficient evaluation of oscillatory integrals over wave boundary elements..
