The explicit (asymptotic) solution of a problem is obtained in a case, when the scattering bodies are far enough from each other. It's established, that the obtained approximate analytical solution of a problem is suitable for calculations with an acceptable exactitude at distances between bodies down to their touch, if the sizes of bodies do not exceed a wave length of a field, incident on a group.

The problem of synthesis of anizotropic impedance plane reflecting a plane uniform wave in a given direction at the desired polarization is solved. The distribution of the impedance is expressed analytically and constitutes a periodic structure. The restrictions on the class of the allowable scattering patterns are formulated for the reactive values of impedance. The reflection coefficients of the nonuniform anisotropic impedance plane are obtained. Numerical results are demonstrated.
