Researchers determine fundamental limits of invisibility cloaks

Researchers in the Cockrell School of Engineering at The University of Texas at Austin have been able to quantify fundamental physical limitations on the performance of cloaking devices, a technology that allows objects to ...

Engineers give invisibility cloaks a slimmer design

Researchers have developed a new design for a cloaking device that overcomes some of the limitations of existing "invisibility cloaks." In a new study, electrical engineers at the University of California, San Diego have ...

Intermediary neuron acts as synaptic cloaking device

Neuroscientists believe that the connectome, a map of each and every connection between the millions of neurons in the brain, will provide a blueprint that will allow them to link brain anatomy to brain function. But a new ...

Building 'invisible' materials with light

A new method of building materials using light, developed by researchers at the University of Cambridge, could one day enable technologies that are often considered the realm of science fiction, such as invisibility cloaks ...

Cloaking device

A cloaking device is an advanced stealth technology that causes an object, such as a spaceship or individual, to be partially or wholly invisible to parts of the electromagnetic (EM) spectrum. Fictional cloaking devices have been used as plot devices in various media for many years, but developments in scientific research show that real-world cloaking devices can obscure objects from at least one wavelength of EM emissions.

In 2008, physicist Michio Kaku predicted that a viable invisibility shield like the ones in Star Trek could emerge from laboratories in a few decades, quoting David Smith of Duke University used a metamaterial to bend light around an object and German scientists have fabricated a metamaterial that could redirect red light round an object.
