Architecture of the proposed compact twisted meta-device for frequency-reconfigurable holography. The meta-device integrates cascaded radiation-type metasurfaces (RA-M) with phase-only metasurfaces (P ...

Scientists unveil metasurface technology, allowing for angle-dependent holograms. The expression "flawless from every angle" is commonly used to characterize a celebrity's appearance. This doesn't ...

Scientists in China have developed a metasurface platform that realizes true three-dimensional (3D) vectorial holography by ...

A chip smaller than one square millimeter stores 160 holographic images at arbitrary 3D coordinates, with each spatial location functioning as an encryption key. (Nanowerk Spotlight) Most storage ...

Metamaterials are an exciting development in materials science with their remarkable mechanical, electromagnetic, and optical properties. They differ from ordinary materials in that their qualities ...

Tailored profiles: The working principle of the new metalaser. The designed geometric phase profile is introduced to the metasurface by rotating the hole in each silicon nitride nanodisk. Then the ...
