The influence of impurities (defects) on the transmission or reflection of wave excitations has been studied on the example of one-dimensional chains of power centers with pair-additive interaction. It is found the possibility of creating the transparency of decorated  by impurities or defects systems by means of special values of parameters adjusted( Ramsauer-Townsend effect). Parameterization of elements of wave circuitry, which are created on the basis of anisotropic and other complex system has been shown.
