Abstract

Magnons, the quanta of spin waves, can potentially be used for energy-efficient data processing. The approach can, in particular, leverage the concept of inverse design, which involves defining a desired functionality and then using a feedback-loop algorithm to optimize device design. Here we report a simulation-free inverse-design device that can implement various radiofrequency components and can process data in the gigahertz range. The device consists of a square array of independent direct current loops on top of a yttrium iron garnet film that generate a complex reconfigurable magnetic medium. We use two feedback-loop algorithms—direct search optimization and a genetic algorithm—to configure the field patterns and create a linear radiofrequency notch filter and a demultiplexer. A device that consists of a square array of independent direct current loops on top of a film of yttrium iron garnet can generate a complex reconfigurable magnetic medium and be used to solve inverse-design problems experimentally without the use of numerical simulations.

一种通用反设计磁振器
磁振子,自旋波的量子,可以潜在地用于高能效的数据处理。该方法尤其可以利用逆设计的概念,即定义所需的功能,然后使用反馈回路算法来优化设备设计。在这里,我们报告了一种可以实现各种射频组件并可以处理千兆赫范围内数据的无仿真反设计装置。该装置由钇铁石榴石薄膜上的方形独立直流回路阵列组成,该薄膜可产生复杂的可重构磁介质。我们使用两种反馈回路算法-直接搜索优化和遗传算法-来配置场模式并创建线性射频陷波滤波器和解复用器。
