Researchers have overcome the limitations of existing metasurface technologies and successfully designed a Janus metasurface capable of perfectly controlling asymmetric light transmission. Metasurface ...

Almost a decade ago, Harvard engineers unveiled the world's first visible-spectrum metasurfaces—ultra-thin, flat devices patterned with nanoscale structures that could precisely control the behavior ...

A research team led by Professor Junsuk Rho at POSTECH (Pohang University of Science and Technology) has developed a secure ...

A new optical device allows researchers to generate and switch between two stable, donut-shaped light patterns called ...

The invention of tiny devices capable of precisely controlling the direction and behavior of light is essential to the development of advanced technologies. Researchers at the Advanced Science ...

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 ...

Scientists have generated ultra-stable, donut-shaped light structures called skyrmions. These innovative beams can carry data ...

The demonstrated QCMs can reconstruct holographic images and display diffraction patterns simultaneously. Silicon nanofins are arranged in the Penrose tiling pattern as illustrated by the 2D color ...
