AbstractCompared to the TM case, the inverse scattering problem for the TE incident field is more complicated, due to its stronger nonlinearity. This work provides an effective method for the reconstruction of 2D inhomogeneous dielectric objects from TE scattering data. The algorithm is the combination of distorted Born iterative method and strong permittivity fluctuation theory. Numerical simulations are performed and the results show that distorted Born iterative method for strong permittivity fluctuation (SPF-DBIM) converges faster and can obtain better reconstructions for objects with larger dimensions and higher contrast in comparison with ordinary distorted Born iterative method (DBIM). Frequency hopping technique is also applied to further increase the contrast.
