Abstract :
This paper deals with a new iterative numerical algorithm for solving an inverse scattering problem: the reconstruction of complex permittivity of inhomogeneous lossy dieletric objects from the scattered near-field measurements. Many authors have studied the numerical methods for solving this kind of inverse scattering problem. We propose an iterative numerical algorithm for electromagnetic imaging based on the perturbation method and Tikhonov´s (1977) regularized method.
