Concurrent Sensing and Communications Based on Intelligent Metasurfaces

Advanced Electronic Materials, EarlyView.
An IM‐assisted concurrent ISAC scheme to exploit the otherwise wasted energy inherent in high‐order 16‐APSK DAM, to realize wireless gesture recognition thereby enabling efficient resource sharing for C‐ISAC. This architecture offers promising opportunities for next‐generation mobile internet, embodied intelligence, smart homes, smart factories, and ...

Deep Tissue Wavefront Estimation for Sensorless Aberration Correction

MATEC Web of Conferences, 2015
The multiple light scattering in biological tissues limits the measurement depth for traditional wavefront sensor. The attenuated ballistic light and the background noise caused by the diffuse light give low signal to noise ratio for wavefront ...

Physics‐Informed Deep Learning Method for Real‐Time Multi‐Harmonic Beamforming Based on Space‐Time‐Coding Metasurface

Advanced Electronic Materials, EarlyView.
This work proposed an unsupervised physics‐informed deep learning method of generating space‐time‐coding metasurface coding patterns for arbitrary single‐ and dual‐beam requirements at each harmonic. This method is specially designed for the coding pattern design task of multi‐bit scenario, and it can effectively handle the optimization trouble caused ...

Versatile Standing Wave Generation Between Arbitrarily Oriented Surfaces Using Acoustic Metasurface Deflectors and Retroreflectors

Advanced Intelligent Systems, Volume 7, Issue 3, March 2025.
A novel method for generating versatile standing wave fields using an acoustic metasurface deflector and retroreflector is introduced. By overcoming traditional constraints of parallel surfaces, the approach enables customizable wave patterns and enhances applications in particle manipulation.
