On March 4, 2026, a groundbreaking research article titled "A Multi-Band Wireless System Based on Microwave Integrated Photonics and Metasurfaces" was published in the esteemed academic journal Nature Photonics. This achievement was the result of a collaborative effort between Researcher Chang Lin's team from Peking University's School of Electronics and the teams led by Professor Song Lingyang and Researcher Di Boya. For the first time, this collaborative team introduced a scalable, unified platform that effectively constructs a parallel wireless communication architecture. This architecture supports multi-band mobile systems ranging from 2G to 6G and beyond, achieved through the integration of photonic integrated circuits with electromagnetic metasurfaces.
