FEATURES OF FORMATION OF BAND GAPS IN COUPLED STRUCTURES BASED ON MAGNONIC CRYSTALS

There are introduced ferromagnetic periodic structures consist of two coupled magnonic crystals and related magnonic and crystal film, separated by a dielectric layer. The dispersion equation made for magnetostatic waves, that propagate in such structures and identified main features of formation band gaps and a comparison with a periodic structure of one magnonic crystal was made.
