Metasurface-Programmable Wireless Network-on-Chip

Advanced Science, 2022
AbstractThis paper introduces the concept of smart radio environments, currently intensely studied for wireless communication in metasurface‐programmable meter‐scaled environments (e.g., inside rooms), on the chip scale. Wireless networks‐on‐chips (WNoCs) are a candidate technology to improve inter‐core communication on chips but current proposals are ...

Single Sensor to Estimate DOA With Programmable Metasurface

IEEE Internet of Things Journal, 2021
With the small sampling length, a novel Direction-of-Arrival (DOA) estimation method based on a single programmable metasurface sensor is proposed in this article. Serving as a physical random sampling receiver, a dynamic metasurface generates series of random radiation patterns to sense the incident signals, which is subsequently processed by the ...

An Intelligent Programmable Omni‐Metasurface

Laser & Photonics Reviews, 2022
AbstractReconfigurable metasurfaces have emerged as a versatile platform for reshaping the wireless environment into a desirable form at low cost. Despite the rapid growth, most of the existing metasurfaces only support reflection operation or transmission operation, only providing service coverage of backward or forward half‐space when they are used ...

Cilia metasurfaces for electronically programmable microfluidic manipulation

Nature, 2022
Cilial pumping is a powerful strategy used by biological organisms to control and manipulate fluids at the microscale. However, despite numerous recent advances in optically, magnetically and electrically driven actuation, development of an engineered cilial platform with the potential for applications has remained difficult to realize1-6.

DOA Estimation with Programmable Metasurface

2020 9th Asia-Pacific Conference on Antennas and Propagation (APCAP), 2020
A novel direction of arrival (DOA) estimation method based on a single programmable metasurface sensor and compressive sensing is proposed in this paper. In comparison with metasuface-based beam-scanning method, metasurface- based compressive sensing for DOA estimation has superior performance with smaller sampling length. A proof-of-concept experiment
