Researchers Develop World's First Antenna For Ultra-Secure 6G

Researchers from the City University of Hong Kong have developed a special antenna that can control all five important aspects of electromagnetic waves using computer software. Interesting Engineering reports: The antenna, which they have named 'microwave universal metasurface antenna,' is capable of dynamically, simultaneously, independently, and precisely manipulating all the essential properties of electromagnetic waves through software control. The antenna adjusts how strong the waves are, their timing, frequency, direction, and even the way they vibrate, all at the same time. It's the first time anyone has made an antenna that can do all these things simultaneously, marking a significant breakthrough in this field.

The antenna is special because it can be used in advanced information systems, like the ones we might have in the future. It's great for handling a lot of data and keeping that data very safe. It can also transfer power wirelessly, meaning it can charge devices without physical connections. One cool thing about this antenna is that it can control the direction of its signals, adding an extra layer of privacy and security. This makes it a good choice for communication systems where we want to ensure nobody can eavesdrop or secretly listen in on our conversations.

Although demonstrated in the microwave band, the UMA's concept can be expanded to terahertz frequencies using specific technologies, enabling applications in augmented reality, holography, integrated sensing and communications for 6G, quantum optics, and quantum information science, noted the researchers in their study. The study has been published in the journal Nature Communications.
