Self‐Imaging Based Programmable Spin‐Wave Lookup Tables

Inclusion of spin waves into the computing paradigm, where complementary metal‐oxide‐semiconductor devices are still at the fore, is now a challenge for scientists around the world. In this work, a wave phenomenon that has not yet been used in magnonics‐self‐imaging, also known as the Talbot effect, to design and simulate the operation of interference systems that perform logic functions on spin waves in thin ferromagnetic multimode waveguides is utilized. Lookup tables operating in this way are characterized by high programmability and scalability; thanks to which they are promising for their implementation in field‐programmable gate arrays circuits, where multiple logic realizations can be obtained.
