For those interested in scientific antiques, scientists at Lawrence Livermore National Laboratory (LLNL) recently released a detailed, super-high resolution retro electromagnetic radiation infographic online. Designed by W.M. Welch Scientific Company in 1944, the “Chart of Electromagnetic Radiations” depicts the entire electromagnetic spectrum and covers the properties, uses, … [Read more...]
Signal-Filtering Algorithms Tackle Smartphone Interference
New signal-filtering algorithms developed to reduce interference in smartphones could provide users with faster performance, longer battery life and fewer dropped calls. Created through a partnership between Kansas State University’s Electronics Design Laboratory and Lawrence, Kan.-based research company Avatekh Inc., the algorithms are intended to more efficiently combat … [Read more...]
U.S. Navy Tests Military Spectrum Sharing Potential
The U.S. Navy has taken a large step towards opening military frequencies for greater commercial use with a recent experiment that evaluated whether or not military and commercial devices can successfully share the same frequency without interference. In a recent test off the coast of Virginia's eastern shore, the Navy activated an AN/SPY1—a powerful naval radar system that … [Read more...]
“Perfect Mirror” Could Increase Efficiency of Fiber Optic Networks, Optical Instruments
Researchers at MIT have created the first perfect mirror using a new method of trapping light that could lead to breakthroughs in the efficiency of fiber optic networks and optical instruments. “For many optical devices you want to build, you need a way to confine light,” Marin Soljačic, an assistant professor in the Department of Physics and a member of MIT’s photonics and … [Read more...]
Physicists Create New Method of Fine-Tuning Topological Insulators
New method of controlling the properties of topological insulators could lead to the development of superfast quantum computers and more energy-efficient transistors, memory devices and magnetic sensors. Physicists at the University of Michigan have developed a more controlled method to fine-tune the properties of topological insulators—materials with the unique ability to … [Read more...]
Study Says Conductive ‘Miracle’ Material Toxic to Humans
New research from Brown University says graphene, an allotrope of carbon with commercial potential in a wide range of applications, may be toxic to humans. Graphene, first isolated by physicists from the University of Manchester, UK and the Institute for Microelectronics Technology, Russia in 2004, is the lightest, strongest and most conductive material known to man, measuring … [Read more...]
New Development Could Simplify Electromagnetic Emissions Testing
A new mathematical model that predicts electromagnetic emissions from printed circuit boards may change the way electromagnetic emissions testing is performed. Developed by researchers from the Agency for Science, Technology and Research (A*STAR) in Singapore and Samsung Electronics, the new mathematical model could help lower costs, improve product design and reduce … [Read more...]
Wireless Signals Track Hidden Moving Objects
A new technology developed by researchers at MIT’s Computer Science and Artificial Intelligence Laboratory could give users the ability to track hidden moving objects using wireless signals in handheld form. The technology—known as Wi-Vi—transmits a low-power Wi-Fi signal and uses its reflections to track moving objects, such as a human body, within a closed room or behind a … [Read more...]
Extension Granted for Ruling on Electronics Use in Flight
A Federal Aviation Administration advisory panel investigating whether to ease restrictions on personal electronic device use during flight is expected to recommend relaxing the ban but has delayed the release of its final report until late September. Comprised of representatives from the Federal Communications Commission, pilot and flight attendant groups, airlines and … [Read more...]
New Security Risk Affects Sensors in Cardiac Devices, Consumer Electronics
Analog sensors within cardiac devices and consumer devices are vulnerable to deliberate EMI signal injection attacks, according to research results recently published by an international team of scientists. Researchers from the University of Michigan, University of Minnesota, University of Massachusetts, Harvard Medical School, Korea Advanced Institute of Science and … [Read more...]
