A new prototype chip-based antenna array that can be installed into a cellular base station smaller than a shoebox could use ultrahigh frequencies to supercharge future wireless networks, reports the MIT Technology Review. Developed by Intel, the technology builds upon research completed last year by Samsung and scientists from New York University. Reportedly capable of … [Read more...]
Flexible Ferrites Offer EMI Shielding and Noise Suppression
Fair-Rite Products Corporation has announced the availability of new flexible ferrites. Available in four thicknesses and six material grades, the RoHS-compliant flexible sheets block noise at lower frequencies and absorb it at higher frequencies. The NiZn ferrite is placed between a 0.01 mm layer of PET film and 0.02 mm adhesive tape. Each sheet can be cut to size enabling it … [Read more...]
Dutch Cable Companies Blame 4G for TV Interference
Cable companies in the Netherlands are claiming 4G wireless networks may be affecting their television broadcast signals. Certain frequencies used by the fourth generation mobile network technology are also employed by television broadcasters to deliver content over cable, the Netherlands Broadcasting Foundation (NOS) said this week. There have been complaints in some cities … [Read more...]
Better Magnetic Spin Wave Control for Electronic Devices
Researchers have developed a method for creating and controlling quick-moving waves in magnetic fields they say could improve communication and information processing in computer chips and other electronic devices. Created by scientists in the Department of Physics at New York University, the new technique relies on “spin waves,” waves that move in magnetic materials similar … [Read more...]
EMS Test Platform Covers Common Frequencies and Field Strengths
EMC test solutions provider Rohde & Schwarz has announced it will be showcasing the R&S CEMS100—the first off-the-shelf solution for EMS testing—and other EMC testing equipment at the International Exhibition with Conference on Electromagnetic Compatibility (EMV 2014) in Duesseldorf, Germany in March. According to the company, the new standardized R&S CEMS100 test … [Read more...]
Graphene Circuit Competes with Silicon Technology
Scientists at IBM have taken their graphene research a step further with the development of what they claim is the world’s most advanced, fully functional integrated circuit made of wafer-scale graphene. According to the researchers, the new graphene-based IC acts as a radio frequency receiver performing signal amplification, filtering and downconversion mixing and is … [Read more...]
European Commission Releases New EMF Exposure Report
A European Commission health committee has released a new updated preliminary study on the health effects of exposure to electromagnetic fields. Published by the Scientific Committee on Emerging and Newly Identified Health Risks (SCENIHR), “Potential Health Effects of Exposure to Electromagnetic Fields” is an update to a 2009 study and aims to take into account technological … [Read more...]
‘Superlens’ Could Lift Restrictions on Wireless Charging
Scientists at Duke University have developed a new method of transmitting power wirelessly over much greater distances than previously achieved, bringing us closer to the possibility of a society where mobile electronic devices can be charged virtually anytime, anywhere. While the idea of wirelessly transferring power to an electronic device is not a new concept, experimental … [Read more...]
RF MEMS Technology May Increase Antenna Efficiency
A technology often used in satellite and defense applications may drastically improve smartphone performance in the near future by increasing antenna efficiency, according to new research from scientists at the University of California San Diego School of Engineering. Antennas in many modern smartphones do not function optimally in 3G and 4G/LTE wireless environments, say the … [Read more...]
RF Testing Laboratory to Open in Louisiana
The Louisiana Technology Park, located in Baton Rouge, La. will soon house a new radio frequency laboratory on its property. Executive committee members of Research Park Corp. voted this month to devote $160,000 to the initiative that would allow local and regional companies to research and test product prototypes in a closer and more convenient location. Currently, though … [Read more...]
