This week at the National Astronomy Meeting (NAM 2015) in Wales, scientists working with the Planck Satellite, including Mike Peel and Paddy Leahy, revealed a new polarization map of the Milky Way in microwaves. This particular view of the electromagnetic loop discovered more than half of a century ago, has never been seen before. “It’s a full sky map showing synchrotron loops … [Read more...]
New Radio Telescope Detects Galaxy From 5 Billion Light Years Away
A new radio telescope in Western Australia, known as Australian Square Kilometre Array Pathfinder (ASKAP), has discovered PKS B1740-517 – a galaxy located more than 5 billion light years away. Six of the 36 dishes on the radio telescope captured signals emitted from PKS B1740-517. This discovery demonstrates that ASKAP can detect galaxies and signals that other telescopes … [Read more...]
‘Unstoppable’ New Hacking Device Steals Encryption Keys Out of the Air
A group of researchers from Tel Aviv University and the Israeli research center have produced a new hacking device that can steal encryption keys “out of the air.” The device cannot be stopped by disabling Wi-Fi networks or turning off Bluetooth because the device doesn’t use standard communication methods to steal data. The device uses radio waves emitted from computer … [Read more...]
Canted Coil Catalog Describes Benefits for EMI/RFI Shielding
Bal Seal Engineering, Inc. released a new 10-page catalog that describes the benefits of canted coil springs for EMI/RFI Shielding. It “provides engineers and designers with detailed information about how canted coil springs can be used to address electromagnetic interference/radio-frequency interference (EMI/RFI) shielding challenges. It describes how the compact, … [Read more...]
High-purity Germanium Detectors Announced
The ORTEC Products Group, a unit of AMETEK Inc., announced its new ‘SP’ series of P-type high-purity Germanium (HPGe) Detectors. The detectors provide advanced resolution at low medium energies for demanding applications, such as radiation detection. “Profile “SP” Series HPGe detectors uniquely employ a low noise back-contact combined with a semi-planar crystal geometry. … [Read more...]
Connector Series Includes EMI Shielding
Mouser Electronics introduces the Amphenol Pegasus series of twist and lock ‘scoop-proof’ connectors with EMI shielding. “EMI shielding is provided by an electroless copper and nickel plate, and a copper alloy spring finger gasket. Tests show greater than 50db of attenuation for low-end signals (<100Mhz) and greater than 40db of attenuation for high-end signals (<1Ghz),” … [Read more...]
Product’s Expanded Features Reveal Hidden Interference
Narda Safety Test Solutions has expanded the features of its Interference and Direction Analyzer (IDA), which will clarify and improve wireless signals. The IDA “Spectrograms with a time resolution of as fine as 1 μs now allow insights into signal structures that were otherwise only possible with large scale lab equipment. This means that interference and hidden transmitters … [Read more...]
New Ceramic Disc Capacitors Save Space and Increase Reliability
Vishay Intertechnology, Inc. announced its new VYI Series of AC-line-rated ceramic disc safety capacitors. The capacitors offer reduced sizes, increased reliability and higher pulse strength up to 10 kV. The VYI Compact Series offers body diameters of 7.5 mm. “Featuring Y5U ceramic dielectrics, the VY1 Compact series is optimized for RFI and AC line filtering applications in … [Read more...]
Ultra-fast Scanning Microscope Introduced
Keysight Technologies introduces the Keysight 9500 AFM System, a new ultrafast-scanning 95000 atomic force microscope. The new system offers new integrated software, a high-bandwidth digital controller and a compact mechanical design. It has ultrafast scan rates up to 2 sec/frame (256x256 pixels) and an auto drive feature that saves users time by automatically setting … [Read more...]
Spaceship Antenna to Prevent Communication Blackouts
A team of scientists from the Harbin Institute of Technology proposed a new spaceship antenna to prevent space communication blackouts. The group’s research has been published in the Journal of Applied Physics. The new antenna can prevent communication blackouts in space when spacecraft are coming back into Earth’s atmosphere. “The proposed technique can maintain … [Read more...]
