Latest Cloak of invisibility Stories
The field of metamaterials has produced structures with unprecedented abilities, including flat lenses, invisibility cloaks and even optical "metatronic" devices that can manipulate light in the way electronic circuitry manipulates the flow of electrons.
With the emergence of metamaterials and transformation optics in the past few years, invisibility has become a scientific possibility that has attracted sustainable research interest.
The first battery-powered cloaking device is being designed by researchers at the University of Texas. The use of an external source of power will greatly expand its bandwidth of operation.
The Chinese government is funding research projects in an attempt to create the world’s first invisibility cloak.
The Information Age will get a major upgrade with the arrival of quantum processors many times faster and more powerful than today’s supercomputers.
Limitations in current cloaking technology allow objects to be temporarily concealed at only narrow wavelengths of light or microwaves, while many newer designs actually make things more visible, experts at the University of Texas acknowledged on Monday.
Researchers at Purdue University have demonstrated a temporal cloaking device for optical communications that bends light to create holes in time, something that could have important implications for sending secret messages over fiber optic cables or thwarting would-be eavesdroppers.
A team of French and German researchers has designed and successfully tested a prototype “invisibility cloak” capable of hiding objects from heat.
By means of special metamaterials, light and sound can be passed around objects. KIT researchers now succeeded in demonstrating that the same materials can also be used to specifically influence the propagation of heat.
Three-dimensional printing is growing in popularity, and the cost for a MakerBot Replicator 2 is now just $2,199. Scientists are also working harder and harder to turn Harry Potter's invisibility cloak into a reality.
