The systematic framework for the proposed multi-liquid identification is depicted in Fig. 1. The system comprises a space-time-coding metasurface illuminated by a feeding pyramidal horn antenna, a ...

Over the past few decades, engineers have developed various devices that can create holograms, three-dimensional (3D) or ...

Chiral light-matter interactions underpin many emerging technologies in sensing, quantum optics, and polarization control. Artificial chiral metasurfaces, which are patterned at nanoscale, can ...
