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...]
Linearization of EMC Amplifiers Continued – Determining Practical Harmonic Levels
Read other posts in the "Elephant in the Test Room" series here.At the time of writing, I am waiting to see if borrowing 3D EM software is on the cards, so let’s postpone progress on Elephant #3 for the time being. I'm quite excited at the prospect of modeling the present automotive emissions test fixture, and equally important, modeling the proposed improvements. In the … [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...]

"IEC 61300-2-43:2014 aims at screening … [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...]
