Infrared-controlled programmable metasurface
Science Bulletin, 2020Programmable metasurface enables controlling electromagnetic (EM) waves in real time. By programming the states of active device embedded in metasurface element, the EM properties of the digital metasurface can be changed quickly without redesigning their structures. However, large numbers of long-distance wires are required to connect the programmable

Single Sensor to Estimate DOA With Programmable Metasurface
IEEE Internet of Things Journal, 2021With 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 ...

3-bit Programmable Reflective Metasurface
2018 12th International Symposium on Antennas, Propagation and EM Theory (ISAPE), 2018A 3-bit programmable reflective metasurface is proposed in this paper. Each unit cell of the metasurface includes 4 pin diodes and by changing the states of the pin diodes, metasurface produces 8 distinct phase responses of $0,\boldsymbol{\pi}/4, \boldsymbol{\pi}/2,3\boldsymbol{\pi}/4, \boldsymbol{\pi}, 5\boldsymbol{\pi}/4,3\boldsymbol{\pi}/2$ and ...

An Intelligent Programmable Omni‐Metasurface
Laser & Photonics Reviews, 2022AbstractReconfigurable 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 ...
