Christian Brull EMI gaskets are conductive hardware designed to conform to joint surface and provide a low impedance path. Compressed between two metal flanges, the gasket presents a complex impedance with resistive, inductive and capacitive properties. This will vary with frequency, materials, compression rate, geometry of the joint, etc. In the meantime, major differences … [Read more...]

German Superconducting Cable Ups Power with Low Transmission Loss
The world’s longest superconducting cable has been integrated into the power grid of a city in Germany, marking the start of a landmark practical test with the potential to save billions of dollars in power industry costs around the world. “This is a good day for . . . the transformation of the energy system in Germany. Today, we start the first practical test of … [Read more...]
Man-Made Electromagnetic Noise Disrupts Bird Navigation
Scientists have known for decades that migratory birds orient themselves using the Earth’s magnetic field in order to fly in the right direction. Now, German researchers have documented for the first time that man-made electromagnetic radiation interferes with these birds' internal compasses. The phenomenon was discovered by Henrik Mouritsen, a professor of neurosensory … [Read more...]
Gigabit Wireless Research Could Open Door to Higher Data Rates
New research on gigabit wireless communications from the University of Bristol in the U.K. could have significant implications for the future of mobile devices. Two research papers presented at IEEE Wireless Communications and Networking Conference (WCNC) in Turkey last week focused on the millimeter-wave band (58-63GHz), in which the researchers believe short-rage gigabit … [Read more...]
New EU EMC Directive Published
The European Union has published the new EMC Directive 2014/30/EU of the European Parliament and of the Council of 25 February 2014 on the harmonization of the laws of the Member States relating to electromagnetic compatibility (recast). The new directive serves as an update to the EMC Directive 2004/108/EC and will be applicable starting April 20, 2016. The primary objective … [Read more...]
Radar Interference Mitigation Strategy to Boost Wind Turbine Installations
A new agreement between a UK air traffic services company and two wind turbine developers could unlock up to 2.2GW of potential new wind energy across the UK. The deal, signed between NATS and wind turbine developers SSE and Vattenfall, secures the funding for alterations to two Raytheon-manufactured radar sites— Lowther Hill and Great Dun Fell—to enable better mitigation of … [Read more...]
European Commission Releases New EMF Exposure Report
A European Commission health committee has released a new updated preliminary study on the health effects of exposure to electromagnetic fields. Published by the Scientific Committee on Emerging and Newly Identified Health Risks (SCENIHR), “Potential Health Effects of Exposure to Electromagnetic Fields” is an update to a 2009 study and aims to take into account technological … [Read more...]
European Government Group Says No to Satellite and Wi-Fi Spectrum Sharing
The intergovernmental coordinating body for European state telecommunications and postal organizations has concluded that wireless devices and satellite radars cannot successfully coexist in the same part of radio spectrum, the head of the body’s technical committee announced Jan. 28. Space News reports the European Conference of Postal and Telecommunications Administrations … [Read more...]
|∆N SASAC | > 4dB, and What’s Next?
Note: This article has been translated from Polish to English. It can be found in its original language in the 2014 Europe EMC Guide. Jan Sroka, Professor, Warsaw University of Technology, Warsaw, Poland ABSTRACT The term "site attenuation" is used in the theory of electromagnetic fields as extension of the term "attenuation," which is well known in circuit theory. The site … [Read more...]
