Improving on the amazing: Scientists seek new conductors for metamaterials
(Phys.org) -- Scientists at the U.S. Department of Energys Ames Laboratory have designed a method to evaluate different conductors for use in metamaterial structures, which are engineered to exhibit ...
Topological transitions in metamaterials
The ability to control the flow of electrons using engineered materials is fundamental to the information technology revolution, yet many properties of matter are still unclear. Now a University of Alberta researcher is closer ...
Novel plasmonic material may merge photonic and electronic technologies
Helping bridge the gap between photonics and electronics, researchers from Purdue University have coaxed a thin film of titanium nitride into transporting plasmons, tiny electron excitations coupled to light ...
Exotic metamaterials will change optics
Duke University engineers believe that continued advances in creating ever-more exotic and sophisticated man-made materials will greatly improve their ability to control light at will.
Artificially structured metamaterials may boost wireless power transfer
Scientists calculate that a "perfect lens," a slab of artificial material engineered to focus electromagnetic fields in ways that natural materials can't, may increase the efficiency of some wireless power transfer systems.
New design for a metamaterial could be far more efficient at capturing sunlight than existing solar cells
Metamaterials are a new class of artificial substances with properties unlike anything found in the natural world. Some have been designed to act as invisibility cloaks; others as superlenses, antenna systems ...
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.
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 ...
New hybrid technology could bring 'quantum information systems'
(PhysOrg.com) -- The merging of two technologies under development - plasmonics and nanophotonics - is promising the emergence of new "quantum information systems" far more powerful than today's computers.
'Darker-than-black' metamaterial could lead to more efficient solar cells
Twisted crystals point way toward active optical materials
(PhysOrg.com) -- A nanoscale game of "now you see it, now you don't" may contribute to the creation of metamaterials with useful optical properties that can be actively controlled, according to scientists ...
Bending light the 'wrong' way
(PhysOrg.com) -- Scientists have tried this with sophisticated meta-materials, but at the Vienna University of Technology (TU Vienna) it has now been done with simple metals; materials with a negative refractive ...
Bending light with better precision
Physicists from the University of California at San Diego (UCSD) have demonstrated a new technique to control the speed and direction of light using memory metamaterials whose properties can be repeatedly changed.
