Measuring low-frequency electric fields remains difficult when traceability, small size, and vector resolution are all required at the same time. A team at Nanyang Technological University, Singapore, ...

Comprising an isotropic field sensor, glass fiber-opticcabling, a miniature tripod, and a processor unit, electric-field analyzer kitsfrom AR RF/Microwave Instrumentation measure modulated electric ...

Accurate measurement of electric field strength is vital for many applications, but existing sensor architectures can be bulky and difficult to calibrate. A project at TU Wien has now developed a new ...

Schematic of the NV and the measurement scheme. a, Schematic drawing of the NV centre with one nitrogen at a carbon lattice site and an adjacent vacancy. b, Simulated absolute electric field 6 μm ...

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 ...

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 ...

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 ...

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 ...
