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...]

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...]
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...]
New SPADs Maximize Precision While Minimizing Noise
Researchers at NIST’s Physical Measurement Laboratory have created a new, highly-efficient single-photon avalanche diode (SPAD) that is able to detect millions of photons per second while limiting noise. SPADs are detectors able to amplify the effect of one photon into a signal large enough to quantify and measure, amplifying miniscule electrical “hits” into an exponential … [Read more...]
National Measurement Standard for Calibration of RF Power Meters in an Ultrahigh-Frequency Band
Japanese researchers have announced the development of a new national measurement standard for the calibration of ultra-high-frequency power meters in the 110-170 GHz band. The new standard, a joint effort between Japan’s National Institute of Advanced Industrial Science and Technology (AIST) and the National Institute of Information and Communications Technology (NICT), was … [Read more...]
