提出了一种基于自旋轨道力矩(SOT)的可重构纳米级自旋波定向耦合器。微磁模拟结果表明，通过SOT反转偶极耦合光波导的全部或部分相对磁构型，可以动态地切换器件的功能和工作频率。利用耦合长度突变的效应，可以实现功分器的功能。提出的可重构自旋波定向耦合器为二维平面磁子集成电路开辟了一条新的道路。
We present a reconfigurable nanoscale spin-wave directional coupler based on spin-orbit torque (SOT). By micromagnetic simulations, it is demonstrated that the functionality and operating frequency of proposed device can be dynamically switched by inverting the whole or part of the relative magnetic configuration of the dipolar-coupled waveguides using SOT. Utilizing the effect of sudden change in coupling length, the functionality of power divider can be realized. The proposed reconfigurable spin-wave directional coupler opens a way for two-dimensional planar magnonic integrated circuits.
