Professor David L. Donoho of Stanford University in California has been awarded the Shaw Prize for mathematical sciences for his work developing algorithms to reduce interference gathered by audio signals. Given by the Hong Kong-based Shaw Prize Foundation, the prize honors recent achievements made by researchers in the fields of astronomy, life science and medicine, and … [Read more...]
Wi-Fi Signals May Stunt Plant Growth, Study Suggests
A science experiment completed by a group of ninth graders in Denmark is gaining worldwide interest from biologists and radiation experts, and may lead to a change in how we view wireless devices in the home. Five girls—Lea Nielsen, Mathilde Nielsen, Signe Nielsen, Sisse Coltau and Rikke Holm—from Hjallerup School in North Jutland, Denmark, began the experiment after … [Read more...]
Glass Windows Boost Mobile Signals
Engineers at Ericsson are experimenting with the concept of embedding antennae within window glass, which could help cell towers better handle multiple simultaneous connections from a single location. In an unofficial interview with a Bloomberg Businessweek correspondent at CTIA Wireless in late May, Mats Guldbrand of Ericsson explained that the new glass could help in … [Read more...]
London Professor Wins AF Harvey Engineering Research Prize for Bistatic Radar Research
Professor Hugh Griffiths of University College London (UCL) has been awarded the A. F. Harvey Engineering Research Prize from the Institution of Engineering and Technology (IET) for his contributions to radar research. “I’m absolutely thrilled. It is an enormous honor to be recognized by one’s peers in this way,” Griffiths said. Griffiths received £300,000 to continue his … [Read more...]
New Electromagnetic Wave Development May Increase Speed, Efficiency of Computer Chips
Researchers at the A*STAR Singapore Institute of Manufacturing Technology (SIMTech) have developed an unusual electromagnetic wave that does not bend or diffract as it travels, which could become an important component in fast, highly-efficient computer chips that use beams of light to carry and process data. Jiao Lin, a physicist at SIMTech, helped to develop the … [Read more...]
Noise-Removal Technology Could Increase Internet Speed Up to 400Gb/s
Researchers from Bell Laboratories in New Jersey have discovered a method to improve data speeds using twin, mirrored beams of light to strengthen data signal quality over longer distances. Typical fiber optic cables use a single beam of light to transmit information and are limited in power and consequentially, distance. While larger distances require more power to transmit … [Read more...]
Printed Technology Captures Electromagnetic Energy for Reuse
Researchers at the Georgia Institute of Technology have developed a method to capture and harness the electromagnetic energy emitted by radio and television transmitters, cell phone networks and satellite communications that could someday lead to self-powering electronic devices. “There is a large amount of electromagnetic energy all around us, but nobody has been able to tap … [Read more...]
Completion of Government Project to Yield Solutions for Wind Turbine-Radar Interference
The U.S. Department of Energy (DOE) and federal agency partners have completed the final operational field test of a two-year, $8 million program to evaluate the physical and electromagnetic interference between air surveillance radar systems and wind turbine farms, and identify possible mitigation techniques. The project was co-funded by the DOE, the U.S. Department of Defense … [Read more...]
New Filter Manufacturing Method Could Improve Performance and Range of Cognitive Radio
Researchers at the Massachusetts Institute of Technology’s Microsystems Technology Laboratory have developed a new method for manufacturing filters for hardware-based cognitive radio applications that could improve performance and enable 14 times as many filters as currently possible to be placed on a single chip. While different proposals for cognitive radio place varying … [Read more...]
Samsung Announces Breakthrough in 5G Mobile Communications
Samsung has announced a significant breakthrough in the development of high-speed 5G mobile communications with the creation of an adaptive array transceiver capable of transmitting data in the millimeter-wave bands at a rate of up to 1.056 Gbit/s and a range of up to 2 km (1.2 miles). Researchers have long believed that millimeter-wave bands offer the broad range of … [Read more...]
