Ultrathin structures that can bend, focus, or filter light, metasurfaces are reshaping how scientists think about optics. These engineered materials offer precise control over lights behavior, but ...

In the race toward practical quantum computers and networks, photons—fundamental particles of light—hold intriguing possibilities as fast carriers of information at room temperature. Photons are ...

THz waves have a plethora of applications ranging from biomedical and medical examinations, imaging, environment monitoring, to wireless communications, because of the abundant spectral information, ...

Researchers have created a bilayer metasurface made of two stacked layers of titanium dioxide nanostructures, opening new possibilities for structuring light. Almost a decade ago, Harvard engineers ...

Harnessing the power of 'phase-change' materials, researchers have demonstrated how reconfigurable metasurfaces -- artificial materials with extraordinary optical properties -- are crucial to the ...

Metasurfaces, whose optical properties are derived from a manufactured nanopatterend surface rather than just component shape or chemical composition, are attractive materials for several optical ...

(Nanowerk Spotlight) Textile engineering has long been a cornerstone of human innovation, from ancient weaving techniques to modern fabric production. However, the integration of textiles with ...

Stranger Things fans will be familiar with this scene: Eleven, a girl with telekinetic powers, stares intently at a Coke can. Without physically touching the can, she completely crushes it using her ...

What are metamaterials and what can they do? The prefix meta (a Greek word meaning ‘beyond’) indicates that the characteristics of the material are beyond what we see in nature. Metamaterials are a ...

Figure 1: Typical applications of metasurfaces in wireless communication include: RIS (Reconfigurable Intelligent Surface-based Wireless Relay Systems), Digit (Digital-Coded Metasurface-Based ...
