The terahertz (THz) band of the electromagnetic spectrum holds immense promise for next-generation technologies, including high-speed wireless communication, advanced encryption, and medical imaging.

Metasurfaces are two-dimensional (2D), nanoengineered surfaces that interact strongly with electromagnetic waves and can control light with remarkable precision. These ultra-thin layers can be used to ...

Metasurfaces are nanoscale structures that interact with light. Today, most metasurfaces use monolith-like nanopillars to focus, shape and control light. The taller the nanopillar, the more time it ...

(Nanowerk News) Metasurface technology is an advanced optical technology that is thinner, lighter, and capable of precisely controlling light through nanometer-sized artificial structures compared to ...

(Nanowerk News) Metasurfaces are nanoscale structures that interact with light. Today, most metasurfaces use monolith-like nanopillars to focus, shape and control light. The taller the nanopillar, the ...

From smartphones and TVs to credit cards, technologies that manipulate light are deeply embedded in our daily lives, many of which are based on holography. However, conventional holographic ...

Given their tiny size, individual atoms are notoriously tricky to see and manipulate, but finding ways to do so would be extremely useful. The invention of the laser in the 1960s eventually led to the ...

Metamaterials usually rely upon a pattern of raised nanostructures manufactured on an optical surface to produce their counter-intuitive properties. A project at the Harvard SEAS lab of metamaterials ...

Researchers developed a metasurface that uses very deep, very narrow holes, rather than very tall pillars, to focus light to a single spot. Metasurfaces are nanoscale structures that interact with ...
