Caption

Rice University graduate student Zhambyl Shaikhanov holds a foil sheet he used to create a “metasurface” — a paper sheet covered with a 2D foil pattern — that an eavesdropper could use in a “Metasurface-in-the-Middle” attack to redirect part of a high-frequency “pencil beam” transmission like those planned for 6G wireless networks.
