Abstract
Spin waves in a magnetic medium show interference phenomena that resemble optical interference and this gives opportunity to rediscover ideas from optical computing and implement them in chip-scale devices. In this talk, I survey our work on the computing application of spin waves for building neuromorphic computing units and radio-frequency components. Focus will be on inverse design, where machine-learning methods are used to engineer the device. We argue that magnonic (spin-wave) devices could be a real alternative to electronic processing where low-power, high-frequency applications are needed.
