A noniterative and efficient method is developed to recover refractive index of a medium which is a function of only two spatial variables from the information on forward scattering amplitude for electromagnetic plane waves incident at different angles and frequencies. To test implementation feasibility of the proposed method and its performance, some preliminary numerical calculations are presented.
