A University of Minnesota light rail reportedly causes electromagnetic radiation and vibrations, which could disturb university research in chemistry and medical departments, the Minnesota Daily reported. For more than a year, Metro Transit and the Metropolitan Council have attempted to reduce the electromagnetic disturbances from the Green Line Light Rail. The University of … [Read more...]
Automatic SAR Measurement Robot Debuts at IMS 2015
This week at the IEEE International Microwave Symposium (IMS), ART-Fi will showcase the “SARborg,” an automatic SAR measurement robot. The SARborg saves time, improves accuracy and repeatability, and is precise with its measurements. “We call it the SARborg, because it’s a robot that runs through batteries of SAR tests completely hands-free. We have essentially roboticized the … [Read more...]
FCC’s Plan to Revitalize AM Radio Concerns Listeners
On May 15, iHeartMedia met with the FCC Media Bureau to discuss the current plan to revitalize AM Radio and to discuss an ex parte letter describing possible changes to AM radio stations. The plan in place will reduce skywave interference protection which make it easier for AM radio stations to operate and give users more flexibility. Jeff Littlejohn of EVP/Engineering and … [Read more...]
Astronomers Discover 17-Year Interference Caused by Microwave Oven
For nearly 17 years astronomers at Parkes Observatory in Australia searched for the reason why radio interference took place during experiments and observations. They discovered early this year that the interference was coming from a microwave oven in the observatory’s kitchen. Parkes Observatory houses one of the best-known radio telescopes in the country. It is used to … [Read more...]
Invisible Objects Created in the Microwave Range Without Metamaterial Cloaking
Physicists from ITMO University, Ioffe Institute and Australian National University have made homogenous cylindrical objects entirely invisible in the microwave range without metamaterial cloaking. Until now, invisibility relied on metamaterial coatings, which can change the direction of light and make light curve around cloaked objects. However, with a new understanding of … [Read more...]
Power Inverter for Energy Grid Testing Bought by U.S. Dept. of Energy
The U.S Department of Energy’s National Renewable Energy Laboratory (NREL) has purchased its second AC/DC High Power Source from AMETEK Programmable Power. The AMETEK system is a high power inverter suited for Energy Grid Testing. If installed parallel with the previous AMETEK unit purchased in 2013, this new system can supply up to 2 MVA, which would make the system the … [Read more...]
Breakthrough in Electromagnetism to Improve Global Communication
Researchers from the University of Cambridge in England have announced an electromagnetic breakthrough – the production of an antenna so small that it can be incorporated into electronic chips. They realized electromagnetic waves are not only generated from acceleration of electronics, but also from symmetry breaking. “Symmetry breaking in physics describes a phenomenon where … [Read more...]
Tech Tidbit: Gwyneth Paltrow has ‘Golden Halo’ in Electromagnetic Image of Aura
Gwyneth Paltrow, a well-known actress, recently had her “aura read” and posted an image of it on her blog ‘Goop.’ The picture was taken by Christina Lonsdale using a rare camera invented in 1970 for the sole purpose of capturing people’s auras. Electromagnetic fields that surround our bodies, also known as auras, are normally invisible; however, they can be illuminated with … [Read more...]
Discovery of New Technology Makes Download Speeds 1,000 Times Faster
Engineers from the University of Utah have discovered a filter for wireless communications that allows users of electronic devices to download data more than 1,000 times faster. Andrew Paulson, project lead and terahertz researcher, has been working on this research for more than two years. Paulson started by considering how to tap into terahertz radiation, which is a band of … [Read more...]
West Virginia Residents Fear ‘Quiet Zone’ May be Abolished
A national radio quiet zone was established in Green Bank, West Virginia in 1958 to house the world’s largest fully steerable radio telescope – the Robert C. Byrd Green Bank Telescope. The telescope successfully works due to the lack of interference from other transmissions. “Electrosensitives,” flocked to the area for more than 10 years. “Electrosensitives” are people who … [Read more...]
