The paper presents a study of solution of inverse medium scattering problems for time-harmonic electromagnetics in 3D. The solution is based on minimization of the misfit function between the observed scattered waves and trial solutions of direct problems for the sought approximate distribution of electric permittivity. The sources of illuminating waves and the observation points of the scattered fields are located in the vicinity of the scatterer. The simulations of the direct problems are performed with the adaptive finite element method. Tests with real- and complex-valued distributions of electric permittivity, and with complete and incomplete measurement data are presented.
