The French Government is now ordering manufacturers to inform consumers how long their electronic devices (cell phones, computers) and appliances are expected to last. “The measure requires manufacturers to inform vendors how long spare parts for an appliance will continue to be produced. The vendor is then required to inform the buyer, in writing. Violators face up to 15,000 … [Read more...]
France Bans Wi-Fi in Childcare Centers
Wi-Fi has been banned in childcare centers, nurseries and schools in France that care for children under six years old, in order to protect young children against exposure to electromagnetic waves and radiation.

UK Homeowners Could Face Criminal Prosecution due to EMI
Homeowners in the United Kingdom who use main wiring systems in their homes (power line networking equipment) could face prosecution if their broadband interferes with radio signals. This method of networking has become a clear alternative to Wi-Fi networks. Ofcom, the communications regulator in the UK, has published a new proposal for a regulation that would allow officials … [Read more...]
The IEEE EMC 2015 Symposium – Why Dresden?
DEAR READERS*, IT’S NOT EVERY DAY you get the country famed for engineering excellence hosting a predominantly US event (the country universally accepted as the economic powerhouse of the world, and famous for her entrepreneurial spirit). So this exceptional event has all the makings for a great meeting of great minds. Germany is the powerhouse that took the EMC industry to … [Read more...]
Applying Stealth Technology to EMC Test Chamber Designs
Tom Mullineaux, President, Lionheart Southwest. Inc Introduction Take a look at any semi-anechoic chamber and they all seem to share the same basic design, that is a long cuboid with six flat faces, five of which are identically clad in RF absorbing materials. However, when utilized for RF immunity testing, the performance of the chamber is pretty much dictated by the … [Read more...]
Assessing Low Frequency Magnetic Field Exposure in Hybrid and Electric Vehicles
Alastair R. Ruddle, Ph.D., and Lester Low, Ph.D. Electrical powertrain technologies are currently of considerable interest within the automotive industry as a way of mitigating some of the inefficiencies of internal combustion engines (ICEs), or even eliminating ICEs completely, as well as eliminating tail-pipe emissions in urban areas. This would offer many important benefits … [Read more...]

Seeding and Harvesting
Mart Coenen For many years national and international norms and standards have been established to make device and product design and manufacturing life easier or at least defined within bounds. In most cases, there is even a life-cycle process for the norms and standards themselves. Old ones fade away and new ones flourish, but some remain everlasting though new insights have … [Read more...]
Characterization of EMI shielding gaskets up to 40 GHz
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...]
