In a study published July 10 on Nature Photonics’s website, Serdar Kocaman, an electrical engineering Ph.D. candidate, and Chee Wei Wong, associate professor of mechanical engineering, demonstrated how an optical nanostructure can be built that controls the way light bounces off it. When light travels, it bends—in technical terms, it disperses and incurs “phase,” an oscillating curve that leaves a trail of information behind it. Those oscillations show an object’s properties, such as shape and size, which can identify it. However, light hits Kocaman’s and Wong’s specially engineered material without leaving a trace. Every natural known material has a positive refractive index: when light hits it, the light bends or refracts. The researchers engineered a structure in which they etched tiny holes, creating a material known as a “photonic crystal” which behaves as though it has zero index – light can travel with an ultrafast

Cisco Boosts Stadium Wifi, Makes MLB slightly More Tolerable For The Internet-Obsessed

---

Anyone who's been in a packed stadium or concert venue knows better than to expect to be able to browse the web or even check email, unless of course your device happens to be compatible with a certain underutilized data-only network. A new initiative from Cisco, however, aims to bring connectivity to the over-saturated masses. The company's Connected Stadium WiFi bundles the Aironet 3500p access point, designed specifically for "high-density stadium and arena deployments," with strategically placed antennas that target fewer seats with the same amount of throughput -- likely similar to the 884-device network AT&T deployed at Cowboys Stadium for Super Bowl XLV. We hope the lighter load placed on carriers -- and already sky high ticket prices -- would help make Connected Stadium a free service, but key words like "purchasing" and "monetizeable" in the networking company's announcement
