      abstract     = {In this paper, an improvement of the inside-outside duality
                      method is considered. The state-of-the-art approximation of
                      the far-field operator via constant interpolation is not
                      sufficient to obtain highly accurate interior transmission
                      eigenvalues especially for larger wave numbers. Therefore,
                      several different approximations of the far-field operator
                      such as Gaussian quadrature, spherical t-design, and Lebedev
                      quadrature are used which are shown to yield superior
                      accuracy for the numerical calculation of interior
                      transmission eigenvalues.},
