Cloaking

Scientists at UC Berkeley have developed a foldable, incredibly thin invisibility cloak that can wrap around microscopic objects of any shape and make them undetectable in the visible spectrum.

A new invisibility cloak developed at the Karlsruhe Institute of Technology (KIT) is reportedly able to hide cylindrical objects up to one inch in diameter, while relying only on common materials like polymers and acrylic paint.

Two scientists at the University of Rochester have taken invisibility cloaking back to basics. Their novel arrangement of four standard, off-the-shelf lenses keeps an object hidden (and the background undisturbed) as the viewer moves up to several degrees away from the optimal viewing angle.

Scientists at Karlsruhe Institute of Technology have developed a method of concealing objects from the sensation of touch that would finally meet the exacting standards of Hans Christian Andersen's fairy tale princess, who felt a single pea prodding her beneath 20 mattresses and 20 feather beds.

Engineers from Duke University have used metamaterials to create an acoustic cloak that makes it appear as if sound waves directed at it were being reflected off a flat surface, regardless of the direction the sound originated from or where the observer was located.

It's often a case of swings and roundabouts. If you save money by buying a house out of town, you spend more time and money commuting. According to a new analysis, the better an object is hidden by an invisibility cloak at one color of light, the easier it is to see at other colors.

A Stanford breakthrough in optical metamaterials could enable fabrication of a wide-spectrum invisibility cloak.

Researchers at Duke University have developed an invisibility cloak that can be made by an entry-level 3D printer.

Scientists are investigating using variations of density in ocean water to cloak oil rigs from dangerous surface waves.

Mathematicians are proposing a cloaking system, which could allow buildings to be rendered "invisible" to earthquakes.

Researchers from Cornell University have demonstrated a working "temporal cloak" that is able to conceal a burst of light as if it had never occurred.

A new "invisibility cloak" utilizes the same effect that causes mirages to appear.
