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
