Researchers from the Johns Hopkins University Applied Physics Laboratory (APL) have announced plans to install an electromagnetic field measurement instrument aboard Virgin Galactic’s SpaceShipTwo as part of the first NASA-funded science mission on a suborbital space plane. The instrument will analyze the electromagnetic fields inside the spacecraft during the 90-minute … [Read more...]
Medical-Grade Heat-Shrink Tubing for Cable Shielding
Methode Electronics, Inc. has released new medical grade shrinkMate™ heat-shrink tubing, which provides easy-to-apply shielding at the cable-to-connector joint, a common point of leakage. Made of clear medical grade polyester, the lightweight tubing shrinks when heat is applied to firm a conductive seal around an object, providing EMI, RFI and ESD shielding without the use of … [Read more...]
Marijuana-Growing Lights Interfere with Amateur Radio
The American Radio Relay League (ARRL), the national association for amateur radio, has filed a formal complaint against a certain type of lighting system used to cultivate marijuana after determining it interferes with MF and HF radio bands. The ARRL said that the ballasts in certain lighting devices like the Lumatek LK-1000, which are increasingly popular among marijuana … [Read more...]

Nickel-Coated Graphite Fiber Particle Additive for EMI Shielding
FigerGraf Materials has introduced a new nickel-coated graphite fiber particle additive for EMI/RFI shielding applications. GrafMat A280N60 offers a 280 micron average particle size, while GrafMat A90N60 is about one-third smaller at 90 microns. The particles of both grades are coated with 60 percent weight addition nickel that encapsulates each particle … [Read more...]
EMC Evaluation and Analysis of Uninterrupted Power Supplies
Sulekh Chand and Nurul Hasan Electronics Regional Test Laboratory (North), New Dehli, India As computer usage increases, stable sources of AC power are a must. The computer needs a continuous 220 V AC source for its operation. In many parts of the world, the public utility supply is not stable, and disturbances and interruptions in power are frequent. To avert possible data … [Read more...]
Watch Webinar on Comparison of Time Domain Scans and Stepped Frequency Scans in EMI Test Receivers
This webinar looks at a CISPR 16-1-1- compliant test instrument with time domain scanning capabilities. The webinar compares the speed and level measurement accuracy of a conventional stepped frequency scan versus an advanced FFT-based time domain scan. It also contains guidance on making optimum use of time domain scans. What will You Learn Behind the … [Read more...]
Double-Duty Electrical Cables Can Store Energy
Scientists at the University of Central Florida have developed a way to both transmit and store electricity in a single lightweight copper wire. Jayan Thomas, a professor at the University of Central Florida, and Ph.D student Zenan Yu created a supercapacitor on the outside of a copper wire as a means to store energy while allowing electricity to continue passing through the … [Read more...]
Federal Regulators to Probe Chrysler Recall
Federal investigators are looking into a 2012 recall to fix airbag issues in over 700,000 sport utility vehicles following consumer claims of inadvertent airbag deployments in several vehicles said to be already fixed. The National Highway Traffic Safety Administration (NHTSA) said in documents filed on June 2 that it had opened a query into a 2012 recall for 744,822 Jeep … [Read more...]
