Chinese scientists have developed a «smart» electromagnetic surface that can convert ambient electromagnetic waves into electrical energy. This, for example, allows Chinese stealth aircraft to convert enemy radar beams into energy to power the aircraft’s systems.
Chinese scientists have developed a «smart» electromagnetic surface that can convert ambient electromagnetic waves into electrical energy. This, for example, allows Chinese stealth aircraft to convert enemy radar beams into energy to power the aircraft’s systems.
As Interesting Engineering writes, such a surface eliminates the need for traditional batteries by harvesting energy directly from radar or environmental signals.
The publication states that this development represents an integration of the principles of electromagnetic engineering and communications.
The innovation focuses on a self-sustaining electronic system that combines wireless information transmission with energy harvesting, which could potentially revolutionize current methods used in electronic warfare and wireless networks.
«Ultimately, this is expected to have a broad impact on 6G communications, the Internet of Things, intelligent stealth technologies, and other related industries,» the researchers added.
The technology uses a reconfigurable intelligent surface (RIS), which is a two-dimensional ray-reflecting material designed to manipulate electromagnetic waves in real time.
In practical applications related to stealth aircraft, this allows you to collect the beams of enemy radar stations to power onboard power plants or communication systems.
In addition to military use, the surface is designed to support 6G telecommunications through integrated sensors and powering satellites or base stations.
The researchers describe the RIS architecture as a low-cost solution for future wireless networks.
The research team suggests that this architecture will eventually enable the creation of environmentally adaptive integrated sensor systems, microbase stations, and self-powered relay systems.
As dev.ua wrote, China has launched the Future Network Test Facility (FNTF). This is a distributed network of data centers that stretches for more than 2,000 km and works almost as efficiently as one giant data center.
