abstract = {This paper investigates the interior transmission problem
for homogeneous media via eigenvalue trajectories
parameterized by the magnitude of the refractive index. In
the case that the scatterer is the unit disk, we prove that
there is a one-to-one correspondence between complex-valued
interior transmission eigenvalue trajectories and Dirichlet
eigenvalues of the Laplacian which turn out to be exactly
the trajectorial limit points as the refractive index tends
to infinity. For general simply-connected scatterers in two
or three dimensions, a corresponding relation is still open,
but further theoretical results and numerical studies
indicate a similar connection.},
