    Abstract

    In this Letter, we report an Airy-like beam of magnetostatic surface spin wave (AiBMSSW) supported on the ferromagnetic film, which is transferred from the optical field. The propagation properties of AiBMSSW were verified with micromagnetic simulation. From simulation results, the typical parabolic trajectory of the Airy-type beam was observed with an exciting source encoding 3/2 phase pattern. The simulation results coincide well with design parameters. Furthermore, simulated results showed that the trajectories of the AiBMSSW could be tuned readily with varied external magnetic fields. This work can extend the application scenario of spin waves.
