Simultaneous SAM and OAM identification is a significant but challenging topic. Chinese scientists have demonstrated that a single spin-decoupled azimuth-quadratic phase metasurface could perform ...

Programmable metasurfaces have emerged as a prominent research focus in the field of artificial electromagnetic materials. By integrating active components such as PIN diodes and implementing ...

Researchers have demonstrated the world's first metasurface laser that produces 'super-chiral light': light with ultra-high angular momentum. The light from this laser can be used as a type of ...

(Nanowerk News) The orbital angular momentum (OAM) of electromagnetic waves — a kind of “structured light” — is associated with a helical or twisted wavefront. The helical modes are characterized by a ...

Researchers have developed a compact quantum detector that makes terahertz radiation much easier to detect. A specially designed metasurface funnels incoming energy into tiny active regions, greatly ...
