asymptotical approach

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.
