A new ultrathin version of ‘Harry Potter-style’ invisibility cloak has been designed by scientists from The Edward S. Rogers Sr. Department of Electrical & Computer Engineering in US, which hides objects over a wide range of frequencies. The invisibility cloaks put forward by scientists up till now have been quite bulky, but now the cloak being just micrometers thick can hide 3-D objects from microwaves in natural environment from all directions. Researchers from the University of Texas at Austin, have used a new, ultra-thin layer called a “meta-screen” and constructed the cloak by attaching 66 micrometer-thick copper tape strips to a 100 micrometer thick, flexible polycarbonate film in a fishnet design.
The meta-screen cloak can only hide objects at specific wavelengths of light and objects are detected when sound, X-rays or microwaves – rebound off its surface. In the new system, researchers have covered the object with a layer of minute antennas that cancels out any waves that bounces off the object, making it undetectable to the radar. Such a clock could be used in military, microscopy, biomedical sensing, and energy harvesting devices.
