Abstract. By successive steps algorithm method the electromagnetic waves of forward and backward directions propagation in multi-layer limited length structure with periodical nonuniformity of meander type is investigated. The frequency dependencies of forward and backward direction wave amplitudes and the transformation of frequency characteristics by barrier quantity variation are investigated. The amplitude wave distribution in inner layers of structure is investigated. It is found two main distributions: sinusoidal and exponential. For large frequency range it is introduced the definitions of strong and weak nonuniformities and the criterion of transition between its is found. The frequency dependencies transformation in large variation interval alignment of layer permittivity is investigated. It is found the compression of frequency spectrum to its lower limit when this alignment is increased.

Key words: wave propagation, multi-layer structure, periodical nonuniformity, frequency spectrum.
