Abstract: 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.
