Star Wars-like Tractor Beam

Authors: George Rajna

Physicists from ITMO University have developed a model of an optical tractor beam to capture particles based on new artificial materials. [45] Researchers from the Structured Light group from the School of Physics at the University of the Witwatersrand in Johannesburg, South Africa, have found a way to use the full beam of a laser single cells in a human body, tiny particles in small volume chemistry, or working on future on-chip devices. [44] This research work by the UEx, which has been published in Scientific Reports, explored the electromagnetic properties of specific materials that can make certain objects invisible when they are introduced into its interior. [43] A research team from ITMO University and the Australian National University has discovered that different metasurfaces exhibit the same behavior provided a symmetry breaking is introduced to their unit cells "meta-atoms."[42] Electron microscopy has allowed scientists to see individual atoms, but even at that resolution not everything is clear.
