Abstract :
A novel inverse scheme applicable in the spectral domain is suggested to find a proper way to remedy the ill-posedness inherent to inverse scattering problems. A cylindrical object with complex relative dielectric constant in arbitrary cross section S is treated. Numerical simulation results are discussed.<>
