With the rapid development of technology, the manipulation of electromagnetic waves and information has become the key to modern lifestyle. This has called for the development of intelligent metasurfaces – which do not require manual intervention to control wave-information-matter interactions. To this end, a group of researchers attempted to study the evolution of intelligent metasurfaces with a vision of the future. They say that intelligent metasurfaces could tremendously benefit the development of 6G wireless communications, green IoT and digital twinning.
The researchers say the development of intelligent metasurfaces has “refreshed human insight into many fundamental laws”, adding that they have led to the development of many new tools and systems, such as cloaking, tunneling and holograms.
“We can imagine that intelligent metasurfaces can learn, make decisions, be self-programming, and learn continuously throughout their ‘lifetime’,” he said in a statement. Statement, Intelligent metasurface is an emerging research direction covering a variety of topics. The researchers say a lot of open questions need to be addressed carefully in the future.
The research was led by Professor Ty Jun Cui of Southeast University and Professor Lianlin Li from Peking University. He has published his paper in e light,
Intelligent metasurfaces have three important properties – digitization, programmability and intelligence. Digitization enables metasurfaces to encode, decode and store digital information. With programmability, the metasurface can realize different functions with a single physical unit. Intelligence means that the metasurface can make decisions, self-program and act consistently without human supervision.
In assessing the future of intelligent metasurfaces, the researchers said the wireless signals already present in our lives could be important for the further development of the field. With the rapid development of artificial intelligence, especially in data mining and knowledge discovery, deep learning has proven to be exceptionally useful in almost every area of science and engineering. They say that deep learning will certainly lead to broad and active research directions. Researchers say intelligent metasurfaces have the potential to revolutionize our lives.
