Computer designs magnonic devices

12.05.2021

Magnonic devices have the potential to revolutionize the electronics industry. Qi Wang, Andrii Chumak (University of Vienna) and Philipp Pirro (TU Kaiserslautern) have largely accelerated the design of more versatile magnonic devices via a feedback-based computational algorithm.

The field of magnonics offers a new type of low-power information processing, in which magnons, the quanta of spin waves, carry and process data instead of electrons. The end goal of this field is to create magnonic circuits, which would be smaller and more energy-efficient than current electronic ones. 

Until recently, the development of a functional magnonic device could take years of trial-and-error. Researchers from the University of Vienna and the TU Kaiserslautern have developed a new computational method to design new devices in a considerably shorter time. Moreover, the efficiency added through this novel inverse design method helps overcome a traditional problem with such devices: they were just suitable for one function only. Now, thanks to the proposed new concept, a primary device could, in principle, be easily modified to perform any function.
