Preliminary results on estimation of the dispersive dielectric properties of an object utilizing frequency-dependent forward-backward time-stepping technique

In this paper, a Frequency-Dependent Forward-Backward Time-Stepping (FD-FBTS) inverse scattering technique is used for reconstruction of homogeneous dispersive object. The aim of the technique is to reconstruct the relative permittivity at infinite frequency, static relative permittivity and static...
