Researchers at the University of Glasgow have developed a new, cost-effective ultra-thin 2D metasurface that could revolutionize 6G satellite communication by manipulating and converting electromagnetic waves commonly used by satellites. This breakthrough, recently published in Communications Engineering, is expected to enhance capabilities in satellite communication, high-speed data transmission, and remote sensing.
The 2D metasurface can convert "linear polarization" electromagnetic waves into "circular polarization," improving the communication quality between satellites and ground stations. This leads to more reliable, high-performance connections while minimizing signal degradation caused by polarization mismatches and multipath interference.
Circularly polarized waves offer significant resistance to atmospheric disturbances, such as rain fade and ionospheric interference, making them ideal for mobile applications and simplifying antenna design for small satellites. Additionally, the material doubles the communication channel capacity and improves satellite tracking, making it a valuable asset for modern satellite systems.
Constructed from patterned copper and only 0.64mm thick, the material can be easily integrated into commercial circuit boards for high-frequency communication. The metasurface works across a broad frequency range from 12 to 40 GHz (Ku, K, and Ka bands), enabling stable connections and enhanced data transmission, and could be produced at low cost using traditional PCB manufacturing techniques.
