Organic chemistry: Leading light waves astray
The development of structured synthetic materials with unusual electromagnetic properties, so-called metamaterials, promises to provide access to special physical effects of great technological interest. Metamaterials have ...
Metamaterials and transformation optics control light on a microchip
Using a combination of the new tools of metamaterials and transformation optics, engineers at Penn State University have developed designs for miniaturized optical devices that can be used in chip-based optical ...
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
Combination of metamaterials and singular optics fueling research innovation
(Phys.org)—Will humans ever control lightning? Could we make the invisible visible, and vice versa?
New 'metamaterial' practical for optical advances
(Phys.org) -- Researchers have taken a step toward overcoming a key obstacle in commercializing "hyperbolic metamaterials," structures that could bring optical advances including ultrapowerful microscopes, computers and solar ...
'Invisibility' cloak could protect buildings from earthquakes
University of Manchester mathematicians have developed the theory for a Harry Potter style 'cloaking' device which could protect buildings from earthquakes.
Pentagon-backed 'time cloak' stops the clock (Update)
Pentagon-supported physicists on Wednesday said they had devised a "time cloak" that briefly makes an event undetectable.
Chemically assembled metamaterials may lead to superlenses
(PhysOrg.com) -- Nanomanufacturing technology has enabled scientists to create metamaterials -- stuff that never existed in nature -- with unusual optical properties. They could lead to "superlenses" able ...
'Mirage-effect' helps researchers hide objects (w/ video)
Scientists have created a working cloaking device that not only takes advantage of one of nature's most bizarre phenomenon, but also boasts unique features; it has an 'on and off' switch and is best used underwater.
Acoustic cloaking device echoes advances in optical cloaking
Optical cloaking devices that enable light to gracefully slip around a solid object were once strictly in the realm of science fiction. Today they have emerged as an exciting area of study, at least on microscopic scales. ...
Researchers create first 3D invisibility cloak
Light speed hurdle to invisibility cloak overcome by undergraduate
(PhysOrg.com) -- An undergraduate student has overcome a major hurdle in the development of invisibility cloaks by adding an optical device into their design that not only remains invisible itself, but also has the ability ...
