Electromagnetic inverse scattering series (ISS) method for sensing 2-D objects buried in layered media with unknown dielectric properties

To reconstruct objects buried in layered media, most of current imaging methods are based on a common assumption that the dielectric properties of layered media are given. However, this assumption is unrealistic in practice. To study a more realistic electromagnetic inverse scattering problem in which the dielectric properties of layered media are not given, an inverse scattering series (ISS) method which has been used in seismic exploration is extended into electromagnetic field. By using the developed ISS method, objects buried in layered media can be imaged without knowing the dielectric properties of layered media a prior. The feasibility of the improved ISS method has been demonstrated by some numerical simulations.
