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.

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 ...

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 ...

"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.

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 ...

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 ...
