Spin wave propagation in different magnonic crystals is considered. Nonreciprocal properties of this waves leads, under certain condi-tions on configuration of structure with magnonic crystal, to displacement of Bragg-like band gap into Brillouin zone. Due to this fact there appears bands with one-directional propagation and bands with negative group velocity.
