Scientists from the Southeast University, the University of Sanio, and the University of Paris-Sacle (CNRS) presented programmable metaps (PM) capable of simultaneously maintaining wireless communication and monitoring environmental changes. The development, published in the journal Nature Communications, opens up new opportunities for the integration of communication and sensory technologies in future 6G networks.
The metaps, known as the “spatio-temporal coding meta-wrap,” surpass traditional mirrors and passive reflectors by not only reflecting electromagnetic waves but also actively altering them using built-in diodes. This enables them to operate simultaneously at the primary frequency of the signal and generate additional harmonics that can be finely configured.
Tai June Tsui, the senior author of the study, stated that the primary objective of the development was to create a single device capable of high-speed data transfer while responding to environmental changes. This approach could greatly streamline network infrastructure, reduce costs, and enhance spectrum utilization efficiency. In experiments, scientists constructed a prototype operating at a frequency of 10.3 GHz, demonstrating its ability to stabilize connections, track object movement, and adjust network operations in real-time.
This technology holds promise for application in various fields, ranging from smart cities and security systems to industrial robotics and autonomous vehicles. Researchers plan to focus future efforts on integrating artificial intelligence for real-time decision-making and enhancing data protection. Ultimately, the aim is to establish intelligent environments that can adapt to user needs, creating safer and more efficient cities.
