A paper published in General Relativity and Gravitation proposes that black holes in a seven-dimensional spacetime do not ...
Meta-holograms, the computer-generated holograms assisted with nano-structured metasurfaces, promise efficient recording of light at the nanoscale. Adopting the multiplexing principle further bestows ...
Layered metasurfaces trained as optical neural networks enable multifunctional holograms and security features, integrating neural computation principles with nanostructured optics to create a ...
