Electric field measurement in power systems underpins critical activities from asset monitoring to safety assurance. Techniques span optical, inductive and microfabricated approaches, each offering ...

As the Parker Solar Probe ventures closer to the sun, we are learning new things about our home star. In a new study, physicists led by the University of Iowa report the first definitive measurements ...

Imagine a satellite, floating in space. How would you measure its voltage? Yes, it probably has a non-zero voltage, a consequence of geospatial electric fields and ion and electron currents. The ...

a: Optically detected magnetic resonance (ODMR) spectra of the NV center for various bias voltages V. b: The local electric field; experimentally and theoretically obtained values are in good ...

For the first time, scientists have measured a long-sought global electric field in the Earth’s atmosphere. This field, called the ambipolar electric field, was predicted to exist decades ago but ...

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 ...
