The Karlsruhe invisibility cloak has been refined so that it is now effective in the visible spectral range. “Seeing something invisible with your own eyes is an exciting experience,” said Joachim Fischer and Tolga Ergin, physicists and members of professor Martin Wegener’s team at Karlsruhe Institute of Technology’s Center for Functional Nanostructures (CFN). In invisibility cloaks, light waves are guided by the material in such a way that they leave the invisibility cloak again as if they had never been in contact with the object being disguised; thus, the...Read full article
