One size cloaks all
A metamaterial invisibility cloak that can adapt to hide different sized objects is demonstrated by in Nature Communications this week. The findings represent a useful advance for more practical applications of metamaterial cloaki ...
Making a better invisibility cloak
The first functional "cloaking" device reported by Duke University electrical engineers in 2006 worked like a charm, but it wasn't perfect. Now a member of that laboratory has developed a new design that ...
MIT physicists suggest a means for creating an electron cloaking device
Exeter physicist bends light waves on surfboards
(Phys.org) -- Scientists across the globe are trying to develop materials that can refract light to create ‘invisibility cloaks’, which are of particular interest to the aerospace industry. ‘Invisibility ...
Thousands of invisibility cloaks trap a rainbow
Many people anticipating the creation of an invisibility cloak might be surprised to learn that a group of American researchers has created 25 000 individual cloaks.
Cloak of invisibility: Engineers use plasmonics to create an invisible photodetector
A team of engineers at Stanford and the University of Pennsylvania has for the first time used "plasmonic cloaking" to create a device that can see without being seen - an invisible machine that detects light. It is the first ...
Al Qaeda suspect's porn film found to contain treasure trove of secret documents
Metamaterials may advance with new femtosecond laser technique
Researchers in applied physics have cleared an important hurdle in the development of advanced materials, called metamaterials, that bend light in unusual ways.
Scientists create first free-standing 3-D cloak
Researchers in the US have, for the first time, cloaked a three-dimensional object standing in free space, bringing the much-talked-about invisibility cloak one step closer to reality.
DNA as invisible ink can reversibly hide patterns
Unveiling malaria's 'invisibility cloak'
The discovery by researchers from the Walter and Eliza Hall Institute of a molecule that is key to malaria's 'invisibility cloak' will help to better understand how the parasite causes disease and escapes from the defenses ...
A breakthrough in superlens development: Cheap, simple lens to let us see a single virus
A superlens would let you see a virus in a drop of blood and open the door to better and cheaper electronics. It might, says Durdu Guney, make ultra-high-resolution microscopes as commonplace as cameras in ...
Researchers transfer the concept of an optical invisibility cloak to sound waves
Progress of metamaterials in nanotechnologies has made the invisibility cloak, a subject of mythology and science fiction, become reality: Light waves can be guided around an object to be hidden, in such a way that this object ...
Invisible computing comes to Asia tech expo
A robotic cook, a colouring book that comes to virtual life and movies that read your mind are some of the innovations on show at a cutting-edge computer technology exhibition in Hong Kong this week.
