Magnetically tunable Airy-like beam of magnetostatic surface spin waves [Early Posting]
In this letter, we report on an Airy-like beam of magnetostatic surface spin wave (AiBMSSW) supported on the ferromagnetic film, which is transferred from optical field. The propagation properties of AiBMSSW were verified with micromagnetic simulation. From simulation results, the typical parabolic trajectory of Airy-type beam was observed by encoding 3/2 phase pattern into excitation sources. The simulation results are coincident well with design parameters. Furthermore, simulated results showed that the trajectories of AiBMSSW beam could be tuned readily with varied external magnetic field. This work can extend the application scenario of SWs.
