It could be years before scientists make cloaks that work for all Steer just a limited part of the light spectrum around objects - and The first working cloaks will be limited that way, he said - able to To a detector that uses microwaves to "see." Shielded object a little smaller than a hockey puck was made invisible Research "for obvious reasons," said David Schurig, a physicist andĮlectrical engineer at North Carolina State University who recentlyĭesigned and helped test a cloaking device. military and intelligence agencies have funded the cloaking "With transformation optics youĬan do many other tricks," perhaps including making things appear toīe located where they are not and focusing massive amounts of energy Professor of electrical and computer engineering at Purdue UniversityĪnd an expert in the fledgling field.
"Cloaking is just the tip of the iceberg," said Vladimir Shalaev, a As a result, things behind the object become visible while the Wavelengths of light to flow around an object like water around a
Known as transformation optics, the phenomenon compels some Material that bends light rays "backward," a weird phenomenon thought Nascent invisibility cloak now being tested, for example, is made of a Light, the fleetest and most evanescent of nature's offerings. Objects inside of them literally invisible under the right conditionsīoth advances reflect researchers' growing ability to manipulate Trying to manufacture rudimentary Harry Potter-like cloaks that make Lin, a scientist who helped create the material at Rensselaer "It's very deep, like in a forest on the darkest night," said Shawn-Yu By voraciously sucking upĪll surrounding illumination, it can give those who gaze on it a Light checks in, but it never checks out. The material, made of hollow fibers, is a Roach Motel for photons. It, making it by far the darkest substance ever made - about 30 timesĪs dark as the government's current standard for blackest black. Paper-thin material that absorbs 99.955 percent of the light that hits Researchers in New York reported this month that they have created a Your Sky makes custom star maps for any location on Earth at any date and time.Scientists Create a Black That Erases Virtually All Light Terranova: a new terraformed planet every day.
