Scientists interpret physics behind invisibility cloaks

Is a perfect invisible cloak theoretically possible? Are there certain wavelengths—such as those in the visible spectrum—that can’t be made invisible? How will using imperfect materials affect the performance of a cloak? ...

Scientists one more step closer to realising invisible technology

A unique computer model designed by a mathematician at the University of Liverpool has shown that it is possible to make objects, such as aeroplanes and submarines, appear invisible at close range.

Engineers create 'optical cloaking' design for invisibility

Researchers using nanotechnology have taken a step toward creating an "optical cloaking" device that could render objects invisible by guiding light around anything placed inside this "cloak."

Negative Refraction of Visible Light Demonstrated; Could Lead to Cloaking Devices

For the first time, physicists have devised a way to make visible light travel in the opposite direction that it normally bends when passing from one material to another, like from air through water or glass. The phenomenon ...

Researchers use heated nanoprobes to destroy breast cancer cells in mice

In experiments with laboratory mice that bear aggressive human breast cancers, UC Davis researchers have used hot nanoprobes to slow the growth of tumors -- without damage to surrounding healthy tissue. The researchers describe ...

The mathematics of cloaking

The theorists who first created the mathematics that describe the behavior of the recently announced "invisibility cloak" have revealed a new analysis that may extend the current cloak's powers, enabling it to hide even actively ...

First demonstration of a working invisibility cloak

A team led by scientists at Duke University's Pratt School of Engineering has demonstrated the first working "invisibility cloak." The cloak deflects microwave beams so they flow around a "hidden" object inside with little ...
