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.
Key words: wave propagation,
periodical structure, spatial modulation.
