Exploiting the orthogonality sampling method to design virtual scattering experiments

The orthogonality sampling method is a recently introduced qualitative method for imaging the location and shape of objects embedded in unknown scenario from the knowledge of their scattered fields. As compared to other qualitative methods, orthogonality sampling is remarkably simpler, as it does not involve the choice of regularization parameters and can be applied also for single incidence. In this contribution, we investigate the possibility of using the method as a new tool to condition the scattering phenomenon and to design virtual scattering experiments. As a matter of fact, the unique features of the orthogonality sampling method could open the way to new and more generally applicable inversion methods based on the virtual experiment framework.
