Researchers at the National Institute for Standards and Technology (NIST) have developed a new metamaterial made of silver, glass, and chromium that allows for the one-way transmission of visible light. Metamaterials are artificial materials engineered, combined and structured, often in patterns, to achieve certain properties. Among other functions, certain metamaterials can … [Read more...]
Valley Current Properties of New Transistor Material Could Outdo Silicon
Researchers at Cornell University have identified and tested a semiconducting compound that could outdo silicon in terms of performance, and could signal the emergence of a new kind of transistor material in electronics. The findings, compiled in the paper, “The Valley Hall Effect in MoS2 Transistors,” published recently in Science, revealed promising conductive capabilities … [Read more...]
Software Optimizes Wind Farm Location to Reduce Telecom Interference
Researchers collaborating on the SOPCAWIND project have developed software to optimize wind farm placement, in order to reduce noise, environmental impact, and telecommunications interference. Wind farms, while a valuable and viable source of energy, reportedly meeting up to 8 percent of Europe’s energy needs, are accompanied by significant drawbacks; namely, noise … [Read more...]
Watch our Webinar on PCB Suppression of ICs with BGA or Multiple Power Rails
Overview: Most EMC design textbooks that cover printed circuit board (PCB) design and layout – including mine – do not cover the special EMC issues associated with Ball Grid Array devices (BGAs), so this webinar covers PCB design techniques that will reduce their emissions and increase their immunity. In particular, how to get good plane meshes under them, and how to … [Read more...]
Study Highlights Need to Re-Evaluate Railway EMC Standards
As part of a recently-completed European Union study on the effects of multi-source electromagnetic interference on trains, a British consulting company has helped redesign the way that conformance to railway electromagnetic compatibility (EMC) standards is determined. The project in question, a two-year study known as TREND (Test of Rolling Stock Electromagnetic Compatibility … [Read more...]

Webinar on PCB Suppression of ICs with BGA or Multiple Power Rails
On June 25, 2014, Keith Armstrong will present a live webinar on “PCB Suppression of ICs with BGA or Multiple Power Rails." Overview: Most EMC design textbooks that cover printed circuit board (PCB) design and layout – including mine – do not cover the special EMC issues associated with Ball Grid Array devices (BGAs), so this webinar covers PCB design techniques that will … [Read more...]
EMI Shielding Compounds for Automotive Radar and Sensing System Components
Thermoplastics compounder RTP Company has developed new EMI shielding compounds ideal for replacing metal or conductive coated plastic housings in automotive sensing systems. Automotive radar and sensing systems designed to maintain vehicle safety and reliability require EMI protection to eliminate “noise” that could interfere with signal processing, the company says. As the … [Read more...]
RF Power Amplifier Reference Solution Speeds Test System Development
Agilent Technologies has introduced a new RF power amplifier manufacturing test solution with envelope tracking capability. The first of the company’s new “Reference Solutions,” it includes a graphical user interface program for simplified solution evaluation, example source code optimized for speed, extremely fast modulation analysis and excellent accuracy and measurement … [Read more...]
Signal Amplifier Design for Mobile Phone Masts to Cut Energy Demands
A breakthrough in the design of signal amplifiers for mobile phone masts could cut the load on power stations by 200MW and reduce CO2 emissions by 500,000 tons per year. Researchers from the University of Bristol and the University of Cardiff say the new amplifier, which was funded by the Engineering and Physical Sciences Research Council (EPSRC), works at 50 percent … [Read more...]
