Abstract

A new approach to solve the inverse electromagnetic scattering problem is presented. A closed-form expansion of radiating and non-radiating sources is used in an equivalent inverse source problem, together with a detection of the minimum convex scattering domain, in order to solve the original inverse scattering problem and to provide a method for electromagnetic imaging. Preliminary numerical investigations show the capabilities of this approach in achieving a good solution to an inverse scattering problem. Furthermore, a comparison between the results obtained by the present method and the simple reconstruction of the scattering object without the scattering support information is also presented, showing an improvement of the results obtained with the method here described.
