This paper treats the full-wave inverse electromagnetic scattering problem of complex permittivity reconstruction in three dimensions. Two Newton-type methods are used to solve this non-linear and ill-posed problem by minimizing a new type of regularized cost function. The Gauss-Newton method and the Broyden-Fletcher-Goldfarb-Shanno quasi-Newton algorithm are compared and results are presented, both from simulated and measured data.
