A new white paper from W. L. Gore & Associates, Inc., “Impact of Materials on Microwave Cable Performance,” presents important factors to consider when selecting microwave/RF cable assemblies to ensure reliable performance. It is critical to identify all of the application constraints that can affect the cables’ overall performance to preserve signal integrity and product … [Read more...]
Doomsday Plane’s Immunity to Electromagnetic Pulse Determined via RS105 Testing
The President’s $223 million doomsday plane is outfitted with an electromagnetic pulse shield to protect its 165,000 pounds of advanced electronics. Thermo-radiation shields also protect the plane in the event of a nuclear strike. The shield was tested by means of RS105 test method specified in MIL-STD-461F, which addresses the risk of radiated exposure to an EMP event. The … [Read more...]
Ferrite Testing Reveals Significant Performance Variations
Recent empirical testing of FerriShield Ferrites shows that there is a notable increase in Ohms of impedance when compared to the exact same competitive alternative. Due to an industry‐wide shift in raw material formulation and manufacturing processes, many RFI/EMI ferrites on the market are delivering lower performance across a wide‐band frequency range. This variation is an … [Read more...]
Growth in Semiconductor Global Sales Through 2013 Projected
The Semiconductor Industry Association has endorsed the World Semiconductor Trade Statistics (WSTS) organization’s mid-year global semiconductor sales forecast which has projected global semiconductor sales to grow to $314.4 Billion, a 5.4 percent increase for 2011. The current view presents an increased projection over the November 2010 WSTS forecast of 4.5 percent growth for … [Read more...]
iNARTE Adds Two EMC Certifications
iNARTE is launching two new EMC certifications this year. The first is EMC DESIGN ENGINEER for engineers whose primary responsibility is to apply EMC principles to electronic design. The other program is for the MIL-STD EMC SPECIALIST. iNARTE is now introducing a special program and short form examination dedicated to the MIL-STDs and the EMC fundamentals that practitioners in … [Read more...]
Giant “Magnetic Rope” Found to Spark Solar Storms
Researchers at George Mason University found that a giant "magnetic rope" made up of twisting magnetic field lines could produce the strong electric currents that trigger solar storms. Due to the twisting, a strong electric current can be carried by the magnetic rope. Theoretically, the electric current could produce enough electromagnetic force to overcome the overlying … [Read more...]
Black Holes Dating Back to Early Universe Discovered
Astronomers have discovered a hidden collection of growing black holes dating back to the early universe, showing, for the first time, that black holes populated the cosmos far earlier than thought. Astrophysicists had theorized that black holes would be found at the center of galaxies very early in the universe. But when astronomers tried to detect them, by looking for X-ray … [Read more...]
Report Unveils 75 Incidences of Electronic Interference on Planes
A report by the International Air Transport Association, a trade group representing more 230 passenger and cargo airlines worldwide, documents 75 separate incidents of possible electronic interference that airline pilots and other crew members believed were linked to mobile phones and other electronic devices. The report covers the years 2003 to 2009 and is based on survey … [Read more...]
Company Delivers Heat Pipes and Structural Components to NASA
Thermacore recently delivered Constant Conductance Heat Pipes (CCHPs) to NASA in support of the agency's Global Precipitation Measurement (GPM) mission. Thermacore also delivered high thermally conductive k-Core® structural components for the agency's Thermal Infrared Sensor (TIRS) program supporting the Landsat Data Continuity Mission (LDCM). NASA's GPM program seeks to … [Read more...]
European Space Agency Shuts Down Illegal Transmitters
An international effort to shut down radio signals that have occasionally been blocking the instrument on ESA’s Soil Moisture and Ocean Salinity (SMOS) water satellite is improving the quality of the mission’s data.The SMOS satellite carries a passive radiometer that operates in the 1400–1427 MHz frequency range (L-band) of the electromagnetic spectrum. It shows ‘brightness … [Read more...]
