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 ...

Chiral metasurfaces can strongly twist the polarization of light, but how this process unfolds in space and time has been unclear. Scientists in China have now used ultrafast electron microscopy and ...

Schematic of the twisted bi-layer metasurface with two design configurations: aligned discs (intrinsic chirality) and displaced discs (unidirectional chirality). Detailed maps of eigenpolarization and ...

Researcher have created a bilayer metasurface made of two stacked layers of titanium dioxide nanostructures, opening new possibilities for structuring light. (Nanowerk News) Almost a decade ago, ...
