A Contrast Source Inversion Algorithm Formulated Using the Log-Phase Formulation

Figure 4

Reconstruction of the simulation no. 2. The dashed lines indicate the positions of the large and the small scatterers. A significant improvement is seen in the permittivity image when the log-phase formulation is used in the algorithm.
