An on-chip mesh routes radio signals using spin waves instead of traditional electricity or wiring.

Modern computers are limited by the heat and resistance of moving electrons through copper and silicon. These magnonic meshes use spin waves in a magnetic material to process information at high speeds. Direct laser writing allows researchers to create these programmable circuits on a tiny scale. This approach could lead to AI hardware that consumes orders of magnitude less power than current chips. It opens the door for high-speed computing that does not rely on the physical limitations of standard electronics.
