Aug 22, 2024: Micromachine twists 2D materials at will (Nanowerk News) Just a few years ago, researchers discovered that changing the angle between two layers of graphene, an atom-thick sheet of ...

In this paper, a wideband tunable reflectarray consisting of a graphene-based metamaterial structure has been developed to generate an orbital angular momentum (OAM) vortex wave in terahertz. In the ...

These exotic light patterns, containing orbital angular momentum, could enable advances in areas like optical trapping, quantum communication, microscopes and data storage. But typically, special ...
