AB  - 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.
