Abstract. By successive steps algorithm method the waves of forward and backward directions propagation in limited length structure with periodical nonuniformity of meander type is investigated. The properties of wave propagation connected with periodicity of structure are explored. It is found the “secondary modulation” effect explained by the multi-resonator properties of structure. It is investigated the forward and backward direction wave amplitudes by the changing of the coordinate or structure slide number and so the average wave number. It is investigated the nonuniformity having similar to saw form and the influence of saw tooth forms on wave propagation conditions. It is investigated the amplitudes distribution in the case of large correlation changing between wave numbers of included in structure media wave numbers. It is investigated the spatial modulation of amplitude. In its character it is found five main regimes. For the explanation of spatial modulation peculiarities it is proposed the analogy with the chain of successive connected related resonators.
