The field of antenna measurements has seen substantial advancements through the development of near-field to far-field (NF-FF) transformation techniques. These methods are vital for accurately ...

Electromagnetic interference (EMI) poses a significant challenge in modern electronic systems, where high-speed digital circuits and densely integrated components increasingly risk mutual disruption.

Southwest Research Institute (SwRI) is expanding its antenna measurement capabilities with a state-of-the-art spherical near-field antenna range. The 1,260-square-foot indoor range, lined with radio ...

When Scotty is beaming up, he’s working in the very far field. Distinguishing between near field and far field conditions is especially important in EMC testing. Published antenna factors and related ...

EMI from on-board DC-DC converters is a common problem with IoT products. These small circuits generally switch between 1 MHz and 3 MHz and use very fast sub-nanosecond edge speeds. The result is ...

Photon offers a line of NIST-traceable camera-based near-field profilers based on the 2/3-inch USBeamPro CMOS camera and the 1/2-inch and 2/3-inch FireWire CCD cameras. Photon Near Field Profilers: ...

The circuit was aimed to measure the variation in magnetic and electric fields by designing an electromagnetic probe with a headphone socket and an output meter. Electromagnetic Field (EMF) – a ...

SwRI’s 1,260-square-foot indoor spherical near-field antenna range is equipped with a built-in overhead half-ton hoist to install and test large antennas up to 10 feet in diameter and 1,000 pounds.
