Control of band gap's in a permalloy Structure by changing the meander profile

Control modes of band gap in meander-shaped permalloy (NiFe) thin films have been investigated by the method micromagnetic modeling. The electrodynamic problem is considered finite element and dispersion characteristics spin waves are obtained when geometrical parameters meander changed. character changes frequency ranges Bragg gaps depending on profile has investigated. results can be used to create devices for microwave signal processing, filters systems with spatio-temporal division signal. Keywords: waves, magnonics, structures, magnon crystal.
