1. near-field - Noun
2. near-field - Adjective
(acoustics) The region within a distance a fraction of a wavelength from a sound source. Accordingly, the outer boundary of the near-field region is closer for high-pitched sound than for low-pitched sound.
(electronics, communication) The region within about half a wavelength from an electrically small antenna. More specifically it is the region within the radiansphere.
Alternative form of near field (in physical acoustics)
Alternative form of near field (in radio-frequency electromagnetic technology)
near-field (not comparable)
In loudspeaker acoustics, referring to a region where the intensity of direct, unreflected sound from the source (such as a loudspeaker) is significantly dominant over any indirect or reflected sound.

Another plus worth noting: Thanks in part to near-field magnetic induction tech, which uses a magnetic field to keep the two earbuds in sync, the BeoPlay E8 rarely experiences connectivity issues. Source: Internet
Both processes for producing electric and magnetic EMR fields have a different dependence on distance than do near-field dipole electric and magnetic fields. Source: Internet
Inductive (magnetic) and capacitive (electric) field strengths are near-field effects, and are only important if the device under test (DUT) is designed for location close to other electrical equipment. Source: Internet
At its peak volume, the Mobile Boombox can serve as a desktop speaker for near-field listening, but can’t come close to filling a room. Source: Internet
He has explored novel near-field inspection techniques involving electric fields over a wide range of frequencies, from DC to optical wavelengths (via focused laser beams) and to X-rays. Source: Internet
Other systems like near-field communications-based (better known as NFC) payments are faster but the feature is available only on expensive smartphones and merchants need to upgrade their PoS devices—and hence may not find mass adoption. Source: Internet
