Scientists and curiosity seekers who want to know what a partially or completely cloaked object would look like in real life can now get their wish -- virtually. A team of researchers at the Karlsruhe Institute of Techno...
The new grant has been made to a team of Imperial College London scientists and engineers, who, in collaboration with scientists at the University of Southampton, will develop new applications for metamaterials that can bend, control and manipulate light and other kinds of electromagnetic waves. Metamaterials is a new, emerging field of science lying at the borders of physics and materials science. The concept relies not on clever chemistry, which is normally used to create new materials, but instead on creating clever patterns on the surface of existing materials, particularly metals.
Looking sharp and looking for light - Berkeley Lab researchers have engineered a new class of bowtie-shaped devices that capture, filter and steer light at the nanoscale. These "nano-colorsorter" devices act as antennae to focus and sort light in tiny spaces, a useful technique for harvesting broadband light for color-sensitive filters and detectors.
Sensors, communications devices and imaging equipment that use a prism and a special form of light -- a surface plasmon-polariton -- may incorporate multiple channels or redundant applications if manufacturers use sculpt...
One of the most basic problems in maths is solving very large linear equations. There's nothing mysterious about them, they simply take time and the more variables there are, the longer it takes. Even a supercomputer would struggle to solve a system of equations that has a trillion variables.
JDSU (NASDAQ: JDSU) (TSX: JDU) today announced that it has licensed patent rights for fundamental picosecond laser technology to Hamamatsu Corporation for the development of microelectronic products.
Xi'an Institute of Optics and Precision Mechanics (XIOPM), Chinese Academy of Sciences recently developed a laser optical tweezers micro-operation instrument for University of Toronto, Canada.
Can an intense laser rip photons into electron-positron pairs? Seeking to shed light on this burning question is the ELI ('Extreme light infrastructure') project, which received EUR 6 million in funding under the...
Terahertz radiation still lies in a metrological no man's land - a metrology gap. The Physikalisch-Technische Bundesanstalt (PTB) can now close this gap.
Whether it's Harry Potter or Star Trek, Hollywood scriptwriters have recognised the storytelling appeal of the 'invisibility cloak'. While most of us are simply happy with the thrill of special effects, one s...
