Concurrent Sensing and Communications Based on Intelligent Metasurfaces

open access: yesAdvanced 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 ...

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

open access: yesAdvanced 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 ...

Propagation of singularities for gravity-capillary water waves

open access: yes, 2019
We obtain two results of propagation for the system of gravity-capillary water waves --- first the propagation of oscillations and decay at the spatial infinity and second a microlocal smoothing effect when the initial surface is non-trapping ...

Design of Compact Liquid Crystal on Silicon Projection Optics Utilizing a Common Freeform Optical Path for Augmented Reality Displays

open access: yesAdvanced Intelligent Systems, EarlyView.
This study presents a compact freeform projection optics using dual wedge prisms for waveguide displays. Unlike previous designs that separate illumination and imaging paths, a freeform optical path integrates both. The system achieves a 32º field of view, 37.5 pixels per degree, and a total volume of less than 2 cm3.
