|Title:||Sharp weyl law for signed counting function of positive interior transmission eigenvalues|
|Keywords:||Interior transmission eigenvalues|
|Publisher:||Society for Industrial and Applied Mathematics|
|Abstract:||We consider the interior transmission eigenvalue (ITE) problem that arises when scattering by inhomogeneous media is studied. The ITE problem is not self-adjoint. We show that positive ITEs are observable together with plus or minus signs that are defined by the direction of motion of the corresponding eigenvalues of the scattering matrix (as they approach $z=1$). We obtain a Weyl-type formula for the counting function of positive ITEs, which are taken together with the ascribed signs. The results are applicable to the case when the medium contains an unpenetrable obstacle.|
