      abstract     = {The method of fundamental solutions is investigated in a
                      stabilized version for the computation of interior
                      transmission eigenvalues in two dimensions for homogeneous
                      and anisotropic media without voids. This approach has
                      already proven to be very competitive in practice for the
                      isotropic framework among regular scattering shapes and
                      keeps predominating through its simplicity as being mesh-
                      and integration free. We give a new approximation analysis,
                      present various numerical results and show that the
                      eigenvalue spectrum for isotropic scatterers is generally
                      different from the corresponding anisotropic borderline
                      cases.},
