The material properties are reconstructed using scattering data from time-harmonic electromagnetic plane waves with the electric field vector perpendicular to the cylinder axis (TE-polarization). An improved algorithm based on a variable metric method is presented to solve the inverse scattering problem. The new method ensures positive values of the reconstructed quantities. This method involves exact first-order gradients. Numerical examples illustrate the efficiency of the algorithm.
