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...]
New Software Detects RF Interference
Delcross Technologies announces its new Electromagnetic Interference Toolkit (EMIT) Version 4.0 software for RF and radar systems. EMIT detects possible RF cosite interference that may occur between two or more radios. “EMIT manages installed RF system performance data, simulates intra-system RF EMI effects, and helps to mitigate EMI issues, resulting in a comprehensive … [Read more...]
EMI Across Randomly-Patterned Multiple Traces on a PCB of an Audio/Multimedia Infrastructure: Crosstalk Performance Vis-à-Vis Smart Handheld Devices
PERAMBUR S. NEELAKANTA*, Ph. D., C. Eng., Fellow IEE and AZIZ U. NOORI, M. S. E. E Department of Computer and Electrical Engineering & Computer Science Abstract In the state-of-the-art wireless devices accommodating a dense layout of copper traces on the associated printed-circuit boards (single and/or multi-layered), is inevitable. Relevantly, considering the baseband … [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...]
Aviation Expert Suggests Electronic Hacking to Blame for Germanwings Crash
A Germanwings plane, traveling from Spain to Germany, crashed into the French Alps last month killing all 150 passengers on board. Many believe the co-pilot, Andreas Lubitz, deliberately crashed the plane. However, one expert says the jet could have been crashed by a hacker instead of the co-pilot. Investigators are certain the plane accelerated during its descent and the … [Read more...]
Programmer Hacks Own Wi-Fi Using Electromagnetic Waves
Jason Cole, a programmer and Ph.D. student at Imperial College in London, created an Android app that allows users to hack their own Wi-Fi using electromagnetic waves. Many believe it’s best to avoid electromagnetic radiation; however, not all believe electromagnetic waves are bad. Electromagnetic waves carry Wi-Fi signals to all electronic devices and are the foundation of … [Read more...]
FCC to Vote on Airwaves Sharing Plan
The Federal Communications Commission (FCC) will vote next month on a plan that will allow companies and wireless carriers to share airwaves with the government. The FCC has been working to increase the spectrum for many years and has set aside frequencies for new Wi-Fi networks. This sharing plan was designed to make more airwaves available for future wireless devices. “The … [Read more...]
Naval Exercise Causes Mobile Phone Black Spot
Plymouth Sound, a bay in England, lost mobile phone signal during a naval exercise last week. The navy said it was testing new ‘communication equipment’ when a mobile phone black spot occurred in the PL1 and PL2 postcodes. Local residents made numerous complains to mobile network operators and as a result, Ofcom, the communications regulator in the United Kingdom, is … [Read more...]
U.S. Navy Tests Electromagnetic Catapult
Traditional steam-powered catapults assist aircraft carriers’ jets and bombers in getting off the ground as quick as possible on a short runway. The U.S. Navy is now testing an electromagnetic version of a catapult on the 337-metre long USS Gerald R. Ford aircraft carrier. “The Electromagnetic Aircraft Launch System (EMALS) uses a burst of electromagnetic energy to launch … [Read more...]
New Bill Could Affect Road Safety Technology
The U.S. government says Wi-Fi contributes to more than $140 billion of economic activity per year and demand is growing for the limited available spectrum, according to CBS news. A new bill has been drafted to fix this problem. Lawmakers plan to open a Wi-Fi space for the public; however, it could negatively impact vehicle-to-vehicle commutation (V2V) technology, which … [Read more...]
