Abstract. Electromagnetic waves of forward and backward directions propagating in the multi-layer structure with periodical nonuniformity having magnetodielectric barriers are investigated by the method of successive steps. It is shown that in this structure the propagation of two independent waves – gyromagnetic and gyroelectric types – is possible. The reflection and propagation of gyromagnetic wave incident  upon the plane boundary between two magnetic media is investigated. The reflected and propagated waves amplitudes, described through the media admittances, are found. The “parameter of discrepancy” consisted of permeability tensor components combination is introduced into consideration. It is shown that in the case when the parameter of discrepancy is negative the gyromagnetic wave propagation is impossible. The balance of energy flow for waves propagating on the structure as a whole is investigated. In large frequency range the frequency dependence of both wave directions is investigated. The appearance of  the  broad line depending on magnetic properties of medium is found in propagation spectrum.

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