Beam of Invisibility
Cloaking technologies have become more of a science fiction creation rather than a reality with recent films, featuring cloaking abilities from using a piece of cloth to more ambitious space vehicles. But recent innovations made some of these fictional technologies become a reality with the research of a specially designed material that is able to camouflage in different forms of light when hit by a beam of invisibility.Hypothetically, invisibility technology can be achieved by navigating light waves in a smooth and certain pattern in a way that waves propagate in their original trajectory rather than with being redirected by obstacles. Previous studies suggest that the idea can be applied on different kinds of waves.Researchers from the Technical University of Vienna formulated an approach to render a subject invisible by using a beam of invisibility. Stefan Rotter, a theoretical physicist at the university said in a statement that, "A light wave can enter and exit the object, but will never pass through the medium on a straight line instead, it is scattered into all possible directions."The main objective of the research is to help the light waves navigate through the object with minimal obstructions as to prevent collision that is disrupting the wave. The conceptual idea is to power up a laser beam to a material from above and charges it to maximum energy, in return altering the material’s composition and properties rendering it transparent from other wavelengths coming from the walls of the material."Every object we want to make transparent has to be irradiated with its own specific pattern, depending on the microscopic details of the scattering process inside," said Rotter while discussing the complexity of formulating the pattern. "The method we developed now allows us to calculate the right pattern for any arbitrary scattering medium."an astonished Rotter said that the concept works and hopes that with reasonable resources and cumulative research, the concept would advance from significant research to industrial applications with telecommunication networks.Want to know more about this awesome device?
