![]() ![]() Then, in 2013, researchers at the University of Texas at Austin developed a method to make objects appear invisible within a limited range of light waves using an ultrathin cloak. In 2006, theoretical physicist John Pendry was one of the first scientists to propose using lenses to bend light to make an object appear invisible. Scientists have long explored how manipulating light waves might be at the root of building an invisibility cloak. Harry Potter and the Philosophers Stone, Chapter 17 (The Man with Two. Why ‘magic’ was needed in Harry Potter’s cloak An Invisibility Cloak was a magical garment which rendered whomever or whatever. “There have been many attempts to make a real-life cloak but there still exist theoretical barriers.” “In this case, wireless sensors are placed on the body,” he said. Kathryn Schulz reviews Philip Ball’s book Invisible: The Dangerous Allure of the Unseen, and considers the history of human fascination with invisibility. In theory, the surface wave cloak also could be used on human bodies, Hao said. “At the moment, the main interest in surface waves is to develop solutions for reducing and mitigating important telecommunications issues.” “We believe that our cloaking structure can improve existing technologies and enables future technological innovation,” he said. The cloak could reduce the scattering of waves used for radio and aerospace communications, said Luigi La Spada, a postdoctoral research assistant at the Queen Mary University of London and first author of the study. When the cloak is not being used, the object along the path of the traveling electromagnetic wave causes the wave to scatter. Otherwise, the electromagnetic waves would bump into the object and scatter in different directions. The researchers found that these layers can hide whatever object they cloak from interacting with electromagnetic waves. The invisible manAdrian, she assumesis gaslighting her in the classic sense of the word he’s making her doubt her sanity and making those around her doubt it, too. The cloak was made out of a gradient-index material with seven superthin layers that each had different electric properties. “The underlying theory can be applied to other wave phenomenon including acoustic and heat waves,” said Yang Hao, professor of antennas and electromagnetics at Queen Mary University of London, who led the study.įor the study, Hao and his colleagues coated a curved metal plate surface, about the size of a tennis ball, with their cloak. In other words, the study suggests a way to make such surfaces invisible. ![]() Their research, published in the journal Scientific Reports last week, demonstrates how a so-called “surface wave cloak” can make curved surfaces appear flat when they come in contact with electromagnetic waves. Now, scientists in the United Kingdom have moved a step forward in the real-world quest for invisibility. Rowling storybooks, the young wizard Harry inherited a magical cloak that could make anyone who put it on instantly invisible. The world doesn’t have a “Harry Potter”-like invisibility cloak quite yet, but various research teams around the world have been making progress in figuring out how to build one.Ĭreating a cloak that can render a person invisible has been the ongoing dream of materials scientists and Harry Potter fans alike. ![]()
