New invisibility cloak combines metamaterials and fancy electronics to be thinner, lighter, more invisible
2013-11-11 18:00:45| Extremetech
A researcher at the University of Texas at Austin has devised an invisibility cloak that could work over a broad range of frequencies, including visible light and microwaves. This is a significant upgrade from current invisibility cloaks that only cloak a very specific frequency -- say, a few hertz in the microwave band -- and, more importantly, actually make cloaked objects more visible to other frequencies. The UT Austin cloak would achieve this goal by being active and electrically powered, rather than dumb and passive like existing invisibility cloaks.

Invisibility cloak made from Teflon can be created in just 15 minutes
2013-09-10 16:54:01| Extremetech
Chinese researchers have succeeded in using a highly novel approach to craft a Teflon-based invisibility cloak in just 15 minutes. The process, called topology optimization, uses computer software to algorithmically and automatically design a material with specific qualities -- such as an invisibility cloak. The design, once desired qualities have been achieved, is then produced using a 3D printer or similar computer-controlled manufacturing device.
