NASA’s Juno spacecraft has unveiled an exciting breakthrough: the discovery of an entirely new type of plasma wave near ...

The near field and the intermediate field are referred to as the Fresnel region (Fresnel zone), and the far field is referred to as the Fraunhofer region or the radiation field. When in close ...

A Fourier transform computation is eventually applied to the 3D near-field to get the far-field radiation pattern. The radiating characterization of the CRPA has been performed with a SATIMO SG24 ...

By measuring the near-field thermal radiation with a varying number of unit cells and the fill factor of the multilayer nanostructures, the team were able to demonstrate that the surface plasmon ...

An explanation of electromagnetic radio waves detailing the near and far fields and how they are propagated.

New 'Near-field' Radiation Therapy Promises Relief For Overheating Laptops Date: April 14, 2009 Source: Lehigh University Summary: Researchers have developed a way to release heat trapped inside ...

Scientists have discovered a new, persistent pattern in Earth's inner radiation belt using data from the twin NASA Van Allen Probes spacecraft. Most surprisingly, the pattern is produced by the slow ...

After building the Yagi, the predicted tuning and impedance matched the real antenna nicely. But what about the radiation pattern? To test that, he used a NanoVNA and a clever test setup.
