This article has been translated from Dutch to English. It can be found in its original language in the 2014 Europe EMC Guide. Mart Coenen, Owner, EMCMCC, the Netherlands The power grid is intentionally meant to distribute electrical energy at the mains frequency, as produced by the electricity generating plants, towards the end-users. The three-phase low-voltage distribution … [Read more...]
New Tool Detects and Traces Electromagnetic Attacks
With the ability to interfere with or damage electronic devices, electromagnetic pulses (EMP) are considered one of the most dangerous threats facing modern electronic systems and infrastructure. Man-made EMPs in particular can be used to deliberately disable power grids and defense and security systems without leaving any indication as to the specific nature or origin of the … [Read more...]
Elephant in the Test Room #1 Continued – The Solid-State Approach
Read other posts in the "Elephant in the Test Room" series here.Recap On this ThreadThe room: MIL-STD RF immunity testing – 1-18GHz 200v/mThe elephant: everyone in the room is aware that a significant fraction of the ‘calibrated’ 200v/m test field is actually created at the wrong test frequency.The culprit: notoriously high ‘start of band’ harmonics produced by all octave band … [Read more...]

FCC May Lift Ban on In-Flight Phone Calls
Federal officials said last week they are considering lifting the ban prohibiting in-flight cell phone use in a controversial move that has drawn protest from both industry groups and the public. While cell phone use would still be restricted during takeoff and landing, the proposal would lift a longstanding Federal Communications Commission ban on phone calls and cellular … [Read more...]
View Our Webinar, Cost-Effective Use of Close-Field Probing Part I
This webinar – number 1 in a series of 2 – describes simple, low-cost, cost-effective, qualitative EMC bench-testing techniques for emissions and immunity, using close-field probes (that many people make themselves) and low-cost portable measuring instruments. These practical techniques can be used in every stage of a product’s life cycle, from proof-of-principle to … [Read more...]
Electromagnetic Cloaking System Cancels Out Radio Waves
A new approach to invisibility cloaking from researchers at the University of Toronto, Canada has yielded an adaptable system capable of shielding objects of various sizes from radar detection. Developed by professor George Eleftheriades and Ph.D. student Michael Selvanayagam of The Edward S. Rogers Sr. Department of Electrical & Computer Engineering, the cloaking system … [Read more...]
