Query: A Density Theorem on the Eigenvalues of Spherically Symmetric Interior
  Transmission Problem in Absorbing Medium   We describe the asymptotic distribution of the eigenvalues of interior
transmission problem in absorbing medium. We apply the Cartwright's theory and
the technique from asymptotic periodic entire function theory. We find a Weyl's
type of density theorem on counting the eigenvalues for spherically symmetric
interior transmission problem in absorbing medium.
