By creating a synthetic surface inspired by lotus leaves, the interdisciplinary team, led by Assistant Professor Heikki Nieminen and Professor Robin Ras, brought new wave phenomena to light.

Researchers developed a model showing the ability of reconfigurable intelligent surfaces to redirect the propagation of radio waves, which could improve the signal. A method to analytically ...

A new system offers an alternative, in that it utilizes acoustic waves which travel across the surface of existing objects. Currently being developed at the University of Michigan, the ...

A method to analytically express the performance of wireless communication systems when using reconfigurable intelligent surfaces (RIS) has been successfully developed by researchers at Tohoku ...

"Conventional brain surface-attached sensors struggled with this because the ultrasound-induced vibrations caused significant noise, making it difficult to monitor brain waves in real-time," said Son.

The product is a lightweight, flexible sheet with metasurface1 structure that can reflect 5G millimeter-band radio waves in specific directions, thereby enabling high-speed, multi-connection ...
