利用微磁学模拟研究了非均匀磁化强度分布对类焦散自旋波光束在未构图磁性薄膜中传播的影响。我们的研究揭示了一个本地可控和可重构的易处理的光束方向。这一特点是用来设计一个设备结合分裂和开关功能的自旋波信号在微米尺度上。验证了自旋波信号通过该器件的相干传输。这证明了磁振子网络的适用性，其中信息被编码在自旋波的相位中。出版社：AIP Publishing
The influence of an inhomogeneous magnetization distribution on the propagation of caustic-like spin-wave beams in unpatterned magnetic films has been investigated by utilizing micromagnetic simulations. Our study reveals a locally controllable and reconfigurable tractability of the beam directions. This feature is used to design a device combining split and switch functionalities for spin-wave signals on the micrometer scale. A coherent transmission of spin-wave signals through the device is verified. This attests the applicability in magnonic networks where the information is encoded in the phase of the spin waves.
