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 ...

Chiral metasurfaces can strongly twist the polarization of light, but how this process unfolds in space and time has been unclear. Scientists in China have now used ultrafast electron microscopy and ...

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.
