A novel technique is developed to reconstruct faulty wiring networks and/or to localize the defects affecting the branches of the wiring network from the reflectometry response. The direct problem (propagation in the cables) is modelled by RLCG circuit model and the Finite Difference Time Domain (FDTD) method whereas the inverse problem is solved using Genetic Algorithms (GAs). In a first step the forward problems is validated by comparison with experimental and simulated data and in a second step the proposed reconstruction method is applied on different configurations and the results are discussed.
