Boundary determination of electromagnetic and Lamé parameters with corrupted data

<p style='text-indent:20px;'>We study boundary determination for an inverse problem associated to the time-harmonic Maxwell equations and another isotropic elasticity system. We identify electromagnetic parameters Lamé moduli these two systems from corresponding measurements. In a first step we reconstruct Lipschitz magnetic permeability, electric permittivity conductivity on surface ideal Then, problems system assuming that data contains measurement errors. For both systems, provide explicit formulas as well its rate of convergence formula.</p>
