A novel inverse scattering approach is developed to the reconstruction of electrical property distributions of a two-dimensional biaxial anisotropic object using time-domain scattering data. The approach is an extension of the forward-backward time-stepping (FBTS) algorithm previously described for an isotropic object. Synthetic examples of inversion are given to assess the effectiveness of the proposed method.
