Inverse scattering of buried inhomogeneous dielectric material coated on a conductor

In this paper, the inverse scattering for buried complex material is investigated. An efficient algorithm is proposed to reconstruct the permittivity distribution of buried inhomogeneous dielectric cylinders coated on a conductor has been proposed. The moment method has been used to transform a set of integral equations into matrix form. The algorithm is based on the unrelated illumination method. The theoretical formulation for electromagnetic inverse scattering is presented and numerical results for objects of different permittivity distributions are given and good reconstruction has been obtained, even in the presence of Gaussian noise in measured data.
