We use the variant of the method of district sources, which was proposed earlier to solve numerically the problem of scattering of electromagnetic radiation by a structure consisting of a finite number of three-dimensional perfectly conducting smooth bodies, to solve a similar problem for the system consisting of a finite number of impedance bodies. The capabilities of the developed computer code are briefly described. Some numerical calculation results are presented, which characterize the influence of the value and type of the surface impedance, as well as deviations of the structure shape from the axisymmetric one, on the scattering cross sections of the structures, in which the distance between the neighboring bodies is much shorter than the wavelength.
