Reconstruction of two-dimensional buried objects by a differential evolution method

The application of a global optimization procedure to the detection of buried inhomogeneities is studied in the present paper. The electromagnetic inverse problem is recast as a global optimization problem and iteratively solved by a differential evolution method. The approach is applied to two-dimensional configurations. The paper provides the mathematical formulation of the method together with a discussion on the application of the stochastic optimization procedure. Finally, the results of some numerical simulations are reported
