Alastair R. Ruddle, Ph.D., MIRA Ltd., Nuneaton, UK Toroidal current transducers are widely used in EMC measurements, both for monitoring currents flowing on single cables or cable bundles and for injecting currents onto such cables or cable bundles. The latter forms the basis of a well-established approach to susceptibility testing (bulk current injection) that is used in the … [Read more...]
EMC Testing above 1 GHz: The Deadline Looms
When first mandated in the 1990s, the stated objective of the EU’s Directive governing EMC was, in broad terms, that commercial and domestic equipment, and certain industrial systems, should neither cause interference or be susceptible to interference. They should not emit radiated or conducted energy at RF frequencies and they should be immune to such emissions, within … [Read more...]
Companion Program
Companion Club Join the other companions at the symposium by registering for the Companion Club. Adults or Jr. companions can register for the Companion Club. Those who are pre-register or plan to register on-site may go directly to the Registration Desk located in the Convention Center to obtain a special Companion Club Registration Packet (on-site registration limited to … [Read more...]
MYTH: Is it Dangerous to use a Phone in a Thunderstorm?
During a thunderstorm, the National Weather Service advises against using a phone. MythBusters Jamie Hyneman and Adam Savage looked into this common safety advice, based on the possibility that lightning could strike whatever building you're inside. The MythBusters zapped a makeshift house with 300,000 volts of electricity to chart lightning's potential path from the ground … [Read more...]
Physicists ‘Entangle’ Two Atoms Using Microwaves
Physicists at the National Institute of Standards and Technology (NIST) have for the first time linked the quantum properties of two separated ions by manipulating them with microwaves. The NIST group is the first to position microwaves sources close enough to the ions, just 30 micrometers away, and create the conditions enabling entanglement, a quantum phenomenon expected to … [Read more...]
College Receives Funding for Microwave Frequency as Treatment for Malaria
Penn State College of Medicine has received Phase II funding through Grand Challenges Explorations, an initiative created by the Bill & Melinda Gates Foundation that enables researchers worldwide to test unorthodox ideas that address persistent health and development challenges. Jose A. Stoute, M.D., associate professor of medicine, microbiology and immunology will continue … [Read more...]
University Chemists Develop Indium-Free Transparent, Flexible Electrodes
The Rice University’s James Tour lab has created thin films that could change touch-screen displays, solar panels and LED lighting. The lab's hybrid graphene film is a strong candidate to replace indium tin oxide (ITO), a commercial product widely used as a transparent, conductive coating. It's the essential element in virtually all flat-panel display and is part of organic … [Read more...]
Hybrid Power Modules Cover 4 – 18 GHz Bandwidth With High Output Power
AR RF/Microwave Instrumentation has introduced a new line of Hybrid Power Modules (HPMs) to its family of solid-state power amplifiers. These HPMs are small, lightweight and compact, yet deliver linear output powers approaching 5 watts across an instantaneous bandwidth of 4 - 18 GHz. They provide gain flatness, can withstand infinite output mismatch and are available in various … [Read more...]
Impulse Noise Simulator with Automatic Ramp Operation
NoiseKen's Impulse Noise Simulator INS-4020 is a further development from the INS series simulators for greater ease of use, durability and reliability with new technologies specifically applied to this new product. The most significant addition is automatic ramp operation in output voltage, pulse repetition period and phase angle placement. The INS-4020 also features floating … [Read more...]
