Joint Quantum Institute Sending entangled beams through fast-light materials Michael Lewis's bestselling book "Flash Boys" describes how some brokers, engaging in high frequency trading, exploit fast telecommunications to gain fraction-of-a-second advantage in the buying and selling of stocks. But you don't need to have billions of dollars riding on this-second securities transactions to appreciate the importance of fast signal processing. From internet to video streaming, we want...

Flat Surface Turned Into Spherical Antenna Using New Device
2014-04-15 16:29:04

By Jason Bardi, American Institute of Physics Broadband transformational optics lens, described in Applied Physics Letters, may lead to antenna dishes that are flat or conform to any surface By depositing an array of tiny, metallic, U-shaped structures onto a dielectric material, a team of researchers in China has created a new artificial surface that can bend and focus electromagnetic waves the same way an antenna does. This breakthrough, which the team is calling the first...

Color Change Mechanism Squid And Octopi
2013-07-26 09:47:07

redOrbit Staff & Wire Reports - Your Universe Online Researchers from the University of California, Santa Barbara (UCSB) have discovered the mechanisms responsible for the dramatic color changes in underwater creatures such as the squid and the octopus. According to UCSB scientists, color in living organisms can be formed in one of two ways - pigmentation or anatomical structure. Structural colors are the result of the physical interaction between light and biological...

Advances in refractometer technology have made urine test strips for sports hydration testing obsolete. Newer dip-style units, like ATAGO's PEN-Wrestling, are more hygienic, more accurate, time saving, and are cheaper than strips in the long run. Bellevue, WA (PRWEB) March 08, 2013 Any high school athletic trainer will tell you that current NFHS (National Federation of State High School Associations) guidelines for high school wrestler weigh-in require a urine specific gravity test done by...

Negative Refraction In Metamaterials
2012-08-02 11:02:12

April Flowers for redOrbit.com - Your Universe Online In a vacuum, light moves extraordinarily fast. Fast enough to circle the Earth seven times before you can literally blink your eye. When light travels through matter, however, it slows down by just less than a factor of five. This refractive index factor is positive in naturally occurring materials, causing light to bend in a particular direction when it passes through matter like water or a glass, for example. In the last 20...

Berkeley Lab Development Holds Promise for Nanolasers, LEDs, Optical Sensors and Photonic Communications The world´s smallest three-dimensional optical cavities with the potential to generate the world´s most intense nanolaser beams have been created by a scientific team led by researchers with the U.S. Department of Energy (DOE)´s Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California (UC) Berkeley. In addition to nanolasers, these unique...

Researchers have shown how arrays of tiny "plasmonic nanoantennas" are able to precisely manipulate light in new ways that could make possible a range of optical innovations such as more powerful microscopes, telecommunications and computers. The researchers at Purdue University used the nanoantennas to abruptly change a property of light called its phase. Light is transmitted as waves analogous to waves of water, which have high and low points. The phase defines these high and low points...
