Model-based inversion of electromagnetic scattering data — An innovative alternate minimization approach

The introduction of a-priori information (e.g., coming from the physics of the problem, iteratively acquired) during the inversion process represents a key tool to be employed to suitably address the ill-posedness and nonlinearity affecting inverse scattering problems. In this framework, this contribution is devoted to introduce an innovative model-based inversion technique which combines on the one hand a suitable description of the problem unknowns and on the other a minimization tool which alternatively retrieves the contrast function and the total field within the investigation domain.
