Abstract. The propagation of surface and backward volume magnetostatic waves in a one-dimensional magnonic crystal in the form of a yttrium iron garnet film with two periodic lattices of grooves with different periods etched on its surface was experimentally studied. It is shown that the form of the frequency dependence of the transmission coefficient of magnetostatic waves in such crystal is not a simple superposition of similar dependences for two magnonic crystals with the same lattice periods.

Key words: magnonic crystal, magnetostatic waves, Bragg resonances.

Financing: The work was carried out within the framework of the state task “Spintronics” (FFWZ-2022-0009).
