US EditionChina Develops Surface that Turns Radar Into Electricity
The RIS technology harvests ambient electromagnetic waves to power devices while enabling integrated sensing and communication, potentially transforming 6G networks and electronic warfare.
- On 6:00am, 28 Dec 2025, Chinese researchers at Xidian University developed a self-sustaining electronic platform that converts ambient electromagnetic waves into electricity and transfers wireless information.
- As part of China’s 6G push, Xidian University team fused communications and electromagnetic engineering to pursue intelligent stealth research and support satellites and base stations.
- Using a two-dimensional reconfigurable intelligent surface and AI-driven optimization, researchers applied multi-agent deep reinforcement learning for beamforming and path planning.
- That capability could power stealth platforms and create intentional radio dead zones, supporting electromagnetic cooperative stealth to reduce radar visibility without traditional batteries.
- Researchers suggest RISs may enable micro base stations, self-powered relay systems, and environment-adaptive integrated sensing systems, impacting Internet of Things and robotic operations.

Only American Leadership Will Prevent the Disaster of Chinese 6G Dominance
For decades, America led the world in technological innovation. But that all changed with the rise of 5G, a development that found the U.S. lagging and reactive. Now, advances in 6G seem set to produce yet another technological transformation—one the U.S. must meet with proactive leadership, not a defensive stance. The stakes are enormous. Whoever masters 6G first will enjoy not just a formidable economic edge, but also a decisive national secur…
China completes first phase of 6G technology trials, defining main technical directions: ministry
China has organized and conducted 6G technology trials for four consecutive years. The first phase of 6G technology trials has now been completed, yielding over 300 advances in key technological areas. The first phase refers to the key technology trial stage, which defines the main technical directions of 6G, CCTV reported on Thursday, citing the Ministry of Industry and Information Technology (MIIT).
