A metal object can be made invisible with the help of ordinary plastic, Pekka Alitalo and Constantinos Valagiannopoulos, researchers from the School of Electrical Engineering, have shown in their ...

These images are from animated computer simulations of a new method — developed by University of Utah mathematicians — for cloaking objects from waves of all sorts. While the new method is unlikely to ...

An object illuminated by an electromagnetic wave can be actively cloaked using a surface conformal array of radiating sources to cancel out scattering. This method is promising as elementary antennas ...

One of the most exciting applications of metaparticles and metasurfaces consists in the magnetic light excitation. However, the principal limitation is due to parasitic extra multipoles of electric ...

(Phys.org)—Ideal invisibility cloaks like those in Harry Potter may be physically impossible, a new study shows. The researchers demonstrate that even the best invisibility cloaks can hide an object ...

Fig. 1. Schematic diagram of an on-chip system consisting of multiple functional modules (a) without the cloak and (b) with the designed thermal-electromagnetic cloak, respectively. (a) A central ...

Muggles are another step closer to donning a real-life invisibility cloak, as scientists have developed a new technology that can make things invisible under the sun. Spectral invisibility cloaking ...

Mathematicians developed a new cloaking method, and it's unlikely to lead to invisibility cloaks like those used by Harry Potter or Romulan spaceships in "Star Trek." Instead, the new method someday ...

Ever since H. G. Wells published The Invisible Man more than a century ago, the prospect of invisibility – or cloaking – has been a mainstay of science fiction. But now physicists say they have ...

Researchers and engineers have long sought ways to conceal objects by manipulating how light interacts with them. A new study offers the first demonstration of invisibility cloaking based on the ...

University of Utah mathematicians developed a new cloaking method, and it’s unlikely to lead to invisibility cloaks like those used by Harry Potter or Romulan spaceships in “Star Trek.” Instead, the ...
