摘要：
In this paper, an iterative multi-resolution method for the reconstruction of the unmeasured components of the equivalent current density is proposed in order to improve the retrieval of the dielectric properties of an unknown scenario probed by interrogating electromagnetic waves. The mathematical formulation, concerned with lossless as well as lossy dielectric scatterers, is provided and the theory is supported by a set of representative examples dealing with synthetic as well as experimental scattering data.
