NASA has many telescopes "working the wavelengths" up and down the electromagnetic spectrum. One of them, the Fermi Gamma-Ray Telescope orbiting Earth, has just crossed a new electromagnetic frontier. "Fermi is picking up crazy-energetic photons," says Dave Thompson, an astrophysicist at NASA's Goddard Space Flight Center. "And it's detecting so many of them we've been able to … [Read more...]
Integrated Design Changes Military Connectors
To meet the prerequisites of commercial aviation with customers like Airbus, Boeing and Dassault, interconnect solutions need to provide full system integration with engine control systems, radar facilities, power distribution networks, in-flight entertainment, wing and engine ice protection mechanisms as well as landing gear and braking control systems. In this context, … [Read more...]
Navy Seeks to Develop Integrated Radar Antennas to Reduce RF Interference
Shipboard radar experts at the U.S. Office of Naval Research (ONR) are asking a select group of 18 U.S. defense contractors to turn their attention to advanced shipboard radar technology that reduces the number of radar antennas on Navy ships by using integrated, multi-function, multi-beam arrays. ONR officials issued a request for information for the Integrated Topside … [Read more...]
Avionics Testing Evolution
Nicholas Wright, EMC Partner AG, Laufen, Switzerland Many disturbance sources can affect the correct functioning and therefore the safety of an aircraft. The latest commercial airliner designs include many technological changes that have necessitated a review of avionic system test requirements. The trend today is to move toward structures made from Carbon Fiber Reinforced … [Read more...]

The HF Current Probe: Theory and Application
This article describes one of the most valuable tools in the EMC engineer's “bag of tricks” – the high-frequency current probe. Current probes are invaluable for measuring high-frequency common-mode (or “antenna”) currents flowing on wires or cables. Experience has proven that poorly terminated (bonded or filtered) cables are the no. 1 cause for radiated emissions failures at a … [Read more...]

Compact Storage Chokes for High Currents
TDK-EPC, manufacturer of electronic components, modules and systems, has extended their range of ERU power inductors with the new EPCOS ERU 20 series. They are differentiated "by a particularly high current capability." At inductance values "of between 1.0 and 35.0 µH, the ERU 20 chokes possess a current capability of between 9.3 and 50.0 A. Their DC resistance values range … [Read more...]
Space Telescope Explores New Energy Extremes
NASA’s Fermi Gamma-ray Space Telescope team plans to expand the telescope’s range into the uncharted electromagnetic range, after the telescope’s more than three years in space. The Large Area Telescope (LAT) “scans the sky every three hours, continually deepening its portrait of the sky in gamma rays, the most energetic form of light.” Most visible light is between two and … [Read more...]
