Abstract
In this paper, the numerical calculation of interior transmission eigenvalues for anisotropic media in two dimensions is considered. This is achieved by reformulating the original problem into a system of boundary integral equations. The resulting nonlinear eigenvalue problem is solved with a recent method using complex-valued contour integrals. Numerical results show that one is also able to calculate complex-valued interior transmission eigenvalues, although the existence of those is still open.
