Researchers in Purdue University’s Robert and Anne Burnett Professor of Electrical and Computer Engineering. They created a new type of invisibility cloak that is simpler than previous designs and works for all colors of the visible spectrum, making it possible to cloak larger objects than before and possibly leading to practical applications in “transformation optics.
the new design is a far simpler device based on a “tapered optical waveguide by tapered waveguide to cloak an area 100 times larger than the wavelengths of light shined by a laser into the device, unlike the previous method that used exotic “metamaterials,” which require complex nanofabrication.
