*N*non-overlapping identical and periodically located 5-shaped two-dimensional scattering centers is considered. When taking into account the transverse dimensions of the chain, this scattering is a multi-channel. The asymptotic value of an impedance of the chain is estimated when

*N*tends to infinity. It is shown that the results a two...
