Invisible Cloak for Military UAV’s
Scientists are working on creating a new design for a technology that redefines what the public views as imaginary. Inspired by the well-known Invisibility Cloak from Harry Potter, electrical engineers at the University of California, San Diego have created a new design for their cloaking device, using a Teflon substrate, studded with cylinders of ceramic, that is thinner than any prior development and does not alter the brightness of light around concealed objects. The Teflon has a low refractive index, while the ceramic’s refractive index is higher, which allows light to be dispersed through the sheet without any absorption. Compared to an invisibility cloak, this technology has not only the ability to conceal, but the ability to increase optical communication signal speed and to collect solar energy.
