Advanced Materials, 2016
Coding acoustic metasurfaces can combine simple logical bits to acquire sophisticated functions in wave control. The acoustic logical bits can achieve a phase difference of exactly π and a perfect match of the amplitudes for the transmitted waves. By programming the coding sequences, acoustic metasurfaces with various functions, including creating ...

Chiral metasurface optomechanics

Conference on Lasers and Electro-Optics, 2019
We report on mechanical action on light polarization, and its back-action effect, in a chiral metasurface. Our thin-film nanostructured semiconductor device may prove of relevance for fast polarization state generation and detection.

Cognitive backscatter metasurface

2024 IEEE 25th International Workshop on Signal Processing Advances in Wireless Communications (SPAWC)
We study a novel spectrum-sharing paradigm for multicarrier cognitive radio (CR) networks, where the conventional primary system employs an orthogonal frequency-division multiplexing (OFDM) modulation scheme, whereas the secondary system is represented by an Internet of Things (IoT) metasurface that concurrently transmits data to a secondary receiver ...
