Cloaking Using Readily Available Materials


Sun, Sep 28th, 2014 11:00 by capnasty NEWS

Wired brings to attention the work being done at the University of Rochester, which has developed a low-tech cloaking system using off-the-shelves materials. Capable of working from different viewing angles, the system operates on four lenses which create a doughnut shaped blindspot where objects can be hidden.

Their simple configuration improves on other cloaking devices, but it’s not perfect. “This cloak bends light and sends it through the center of the device, so the on-axis region cannot be blocked or cloaked,” said Choi. This means that the cloaked region is shaped like a doughnut. He added that they have slightly more complicated designs that solve the problem. Also, the cloak has edge effects, but these can be reduced when sufficiently large lenses are used.
