RT Journal Article T1 Hybrid topological derivative-gradient based methods for nondestructive testing A1 Carpio Rodríguez, Ana María A1 Rapún Banzo, María Luisa AB This paper is devoted to the reconstruction of objects buried in a medium and their material properties by hybrid topological derivative-gradient based methods. After illustrating the techniques in time-harmonic acoustic problems with different boundary conditions and in electrical impedance tomography problems with continuous Neumann conditions, we extend the hybrid method for a realistic model in tomography where the boundary conditions are given at a discrete set of electrodes.
