Abstract :
A new iteration method for electromagnetic inverse scattering is presented. This method, called the variational Born iteration method (VBIM), shows its efficiency much better than the distorted Born iteration method. VBIM has also been used for hybrid iteration inversion. Moreover, the analytic characteristics of the numerical mode match (NMM) solution were used in the inversion integral equation to speed up the calculation. Some procedures to gain the stability of the inverse solution are also discussed
