Combination of the asymptotical approach for solving the initial diffraction problem and numerical solution of the received integral equations is applied to creating the media with desired refraction coefficient. The obtained refraction coefficient, close to the desired one, is created by change of electrophysical and geometrical parameters of small particles embedded in given media. The initial diffraction problem is considered under the assumptions ka > , where a is the size of the particle and d is the distance between the neighboring particles. Impedance boundary conditions are assumed on the boundaries of small particles. The results of numerical simulation show good agreement with the theory. They open a way to numerical implementation of the method for creating media with a desired refraction coefficient.
