EMC engineering has come a long way since Mike Violette, president of Washington Laboratories, first entered the field after graduating from Virginia Tech in May 1984. In honor of the 20th anniversary of the Gaithersburg, Md.-based laboratory, Violette looks back on some of his more memorable projects – from getting up close and personal with the Liberty Bell to gastronomical … [Read more...]

Using a Comb Generator with a Pair of Current Probes to Measure Cable Resonance
(A Useful Technique When a Tracking Generator is not Available) A comb generator RF source can be a handy substitute when a tracking generator is not available on a spectrum analyzer, EMC consultant Doug Smith says in this month’s Technical Tidbit. In this case, a USB powered comb generator RF source is used to supply the signal used to measure the resonant frequencies of a … [Read more...]

Movement to Tighten Up Regulations on EMI above 1GHz Could Be Spreading
High-frequency EMI radiated by electronic devices, noise above 1GHz, is attracting increased scrutiny, reports Nikkei Electronics Asia. Revisions to EMI standards have expanded the scope of regulated frequencies into the GHz waveband. EMI standards are getting increasingly tough with recent revisions, striving to minimize interference in the GHz communication wavebands used by … [Read more...]
Aircraft, Satellites Could Use Nanotubes for EMI Shielding
Aerospace and aircraft companies as well as the military have been challenged to find ways of effectively shielding sensitive electronic equipment, such as radar and radios from electromagnetic interference without adding a lot of weight to aircraft and satellites (the more massive they are, the more fuel they need to stay in the air or achieve orbit, respectively). Whereas EMI … [Read more...]
Unmanned Chopper Finds Improvised Explosive Devises
The U.S. military is testing an unmanned helicopter that can detect electromagnetic emissions from Improvised Explosive Devises (IEDs). Roadside bombs have long represented the greatest killer of soldiers in Iraq and Afghanistan, but there's hope beyond the sturdy little demolition bots that already work with their human handlers. The Pentagon now has two aerial drones on the … [Read more...]
DOD Tests, Buys New ISO 18000-7 RFID Tags
After testing the new active 433 MHz tags for electromagnetic interference, the U.S. military has placed orders for the devices, which could cost half as much as their predecessors.This first order of RFID technology complaint with the ISO 18000-7 standard placed by the U.S. Department of Defense (DOD) is planned for a November 2009 delivery. The sources are Unisys, Savi, … [Read more...]
Airport Test Uses Electromagnetic Radiation to Find Liquid Explosives
Since a failed terrorist attack in 2006, plane passengers have not been able to carry bottles of liquid through security at airports, leaving some parched at the airport and others having expensive toiletries confiscated, but work by a group of physicists in Germany is paving the way to eliminate this necessary nuisance. An article in IOP Publishing's Superconductor Science and … [Read more...]
