Finding scattering data for a time-harmonic wave equation with first order perturbation from the Dirichlet-to-Neumann map

Résumé

We present formulas and equations for finding scattering data from the Dirichlet-to-Neumann map for a time-harmonic wave equation with first order perturbation with compactly supported coefficients. We assume that the coefficients are matrix-valued in general. To our knowledge, these results are new even for the general scalar case.
