British engineers have reportedly discovered a way to bypass the Faraday cage effect that prevents the entry or escape of an electromagnetic wave through a metallic enclosure. According to a statement released by developer The Technology Partnership (TTP), new patent-pending Fluxor technology creates a “window” for electromagnetic transmission of power and data by applying a … [Read more...]
New Device Manipulates Millimeter Waves for Smaller Short-Distance Communication Systems
Researchers in Singapore have created a device capable of manipulating radio frequency signals that could lead to the development of smaller short-distance communication systems. Known as a subharmonic passive mixer, the device, built by Rui Li and her colleagues at the A*STAR Institute of Microelectronics, can convert millimeter waves from one wavelength to another. … [Read more...]
FAA Panel Advises Lifting Flight Restrictions on Electronics
A Federal Aviation Administration advisory committee tasked with investigating flight restrictions on personal electronic devices has concluded that most electronics, including those connected to onboard Wi-Fi, can be safely used during all portions of flight on most U.S. passenger aircraft. Established last year, the 28-member panel is comprised of representatives from the … [Read more...]
Radio Test System for Evaluation of Military and Software-Defined Radios
Aeroflex Inc., a provider of high performance microelectronic components and test and measurement equipment, has released the new Aeroflex 7215 Configurable Automated Test Set, a radio test system designed for production and depot-level testing of military and software-defined radios (SDR). According to the company, the new 7215 radio test system includes a high resolution … [Read more...]
FAA Panel to Release Device Use Recommendations
A Federal Aviation Administration advisory panel investigating whether or not to relax the rules surrounding personal electronic device use on airplanes is expected to wrap up their inquiry next week, The New York Times reported in a recent article. Citing information from several members of the panel who requested anonymity, The New York Times said that the new guidelines are … [Read more...]
Spring Contacts for Shielding, Grounding and Electrical Connection Applications
Harwin, a manufacturer of electrical and electronic interconnect solutions, has expanded its range of EZ-Spring Contacts with new contact styles and heights. Part of the EZ-BoardWare range of PCB hardware products, the surface mount spring contacts—also known as spring fingers or grounding contacts—are now available in 15 different sizes, ranging from 1.70mm to 7.25mm free … [Read more...]
Researchers Control Electromagnetic Waves with Help from 3-D Printer
A team of scientists from the University of Texas at El Paso have developed a way to control electromagnetic waves in three-dimensional space using plastic metamaterials created with a 3-D printer. “When you fold electromagnetics into three dimensions, the components interfere with one another, and it becomes a confusing electromagnetic mess where nothing will work—like when a … [Read more...]
Microwave Oven Powers Small Devices with Electromagnetic Energy
Scientists in Japan have discovered a way to run kitchen appliances using electromagnetic energy scavenged from microwave ovens. While the majority of radiation generated by the common kitchen appliance is directed at the food inside the device, a portion of the energy can still escape through the gap around the door and through the metal-meshed window. So, for consumer … [Read more...]
New Board Level Shielding Products Announced
TE Connectivity has announced the availability of new board level shielding (BLS) products, stamped or drawn one- and two-piece metal cages that help provide isolation of board level components, minimize crosstalk and reduce EMI susceptibility without impacting system speed. Ideal for use in smartphones and tablet computers, the new BLS products will use standardized features, … [Read more...]
Compact EMC Filters with Low Leakage Current
Electronics specialist TDK Corporation has released a new series of EPCOS EMC filters. Applications for the new filters include converters and power electronics systems. The B84142A*166 series of compact 2-line filters features different models designed for rated currents of 10 A, 16 A, and 30 A at a rated voltage of 250 V AC (50/60 Hz).
