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...]
Congress Pushing for Grid Vulnerability to EMP Assessment
Congress has expressed interest in learning more about the capabilities of America’s adversaries to damage the nation’s power grid. Watchdog.org reports an intelligence authorization bill passed by the House of Representatives last month includes a provision directing the director of national intelligence to submit to Congress “a report on the threat posed by man-made … [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...]
RF Conformance Test System for Vehicle-to-Vehicle Applications
Rohde & Schwarz has introduced the new R&S TS-ITS100, the world’s first fully automated test system for standard-compliant testing of RF components for vehicle-to-vehicle communications and intelligent transport systems (ITS) in line with IEEE 802.11p. With its compact size, the RF conformance test system can be used throughout the entire value chain, from R&D to … [Read more...]
Korean Study Reveals Negative Effects of Terahertz EM-Waves in Living Organisms
In a premiere study on the effects of teraherz waves on living organisms, scientists in Korea have observed heightened skin inflammation in mice exposed to strong terahertz waves, signaling the potentially dangerous side effects of these waves in other living beings, such as humans. Terahertz wavelengths, located between infrared waves and microwaves on the electromagnetic … [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...]
ESA Battles Interference Affecting Climate Change Satellites
The European Space Agency (ESA) announced that it was recently forced to change the frequencies used by some of its satellites in order to work around interference emitted from Earth-bound wireless communication installations, some of which are illegal. At a recent briefing to London’s Royal Society dedicated to discussing the results of ESA satellites compiling data on … [Read more...]
NATO Denies Involvement in Aircraft Radar Jamming
A statement from NATO made public last week denies involvement in the brief disappearance of dozens of aircraft from air traffic control radars in several European countries earlier this month. Air-traffic controllers in Austria, Germany, Slovakia and the Czech Republic reported data on the position, direction, height and speed of aircraft disappeared temporarily from radar … [Read more...]
Paradoxical Laser System Shuts Off with Energy Boost
Researchers from Princeton University and Vienna University of Technology have demonstrated a laser system that paradoxically turns off, rather than becoming brighter, when more power is added. The system is comprised of two lasers measuring roughly the width of a human hair that are separated by a distance 50 times smaller than the lasers themselves. In the lab, researchers … [Read more...]
Rugged 2 W, 40 GHz Attenuators Suit RF-Related Applications
Pasternack Enterprises has introduced a new line of high frequency, millimeter wave attenuators for applications requiring reliable broadband performance ranging from DC to 40 GHz. Ideal for many RF-related applications including test labs, research facilities, military electronics, telecommunications equipment, security devices and production line testing, the new 40 GHz … [Read more...]
