factor, and we get the far field response in half space (p 2 ): r a v p r 2 2 0 2 =, far-field response in a half space (r > 6a) Figure 4. Normalized loudspeaker response at different frequencies (ka = 1, 5, 10) in a transition region from near-field to far-field. .

Near-field microphones can help you do this. Near-field mics can be positioned in the same way that you would position most other dynamics and condensers when miking up close. They are more protected from wind blasts than far-fields, and they retain a balanced sound from within 1.5 feet (0.5 m) to the source.Dr Martin Smalley, University of York.This video was recorded by the Department of Physics, University of York as part of the Video Capture pilot funded by t...

Near field vs Far-field Studio Monitors. Nearfield and farfield studio monitors refer to the position of the speakers relative to the listener. Nearfield monitors are meant to be positioned close to the listener, typically 1-2 meters away. They are designed to minimize sound reflections from the walls and other surfaces in the room.For certain applications, installations and upgrades as well as for lower frequencies and real-time measurements far-field is the most suitable option. Also, far-field configurations work best for indoor or compact range testing. However, for high gain antennas the most appropriate option is near-field configurations: For high directivity ...As we bring the antenna above the ground (in this case PEC) we see the distance where the field exhibits the far-field behavior is at a larger distance compared ...Results: In healthy patients, significant differences in the far-field to near-field EGM activation onsets were observed between right atrial (14.7 ± 2.7 ms), right ventricular (36.3 ± 8 ms), and left ventricular (57.8 ± 10.3 ms; P < .001) pacing. In the derivation ICD cohort, the median far-field to near-field onset delay was significantly ...Coupling between the source and the eigenmodes inside the resonant metalens efficiently scatters off near-field information, which is encoded in time and recorded by far-field antennas in ...

The near-field and far-field regions correspond to the electromagnetic fields nearer and farther from the antenna, respectively. The most commonly-used parameter to define near-field vs. far-field regions is signal wavelength. Let’s take a closer look at the near-field vs. far-field regions associated with antennas.Seismological Research Letters, 68 (1), 199–222. Near-field earthquakes have some characteristics that differ them from far-field ones. These earthquakes have higher accelerations and restricted ...Abstract. The reason for the strong interest in the electrodynamic properties of metal nanoparticles (i.e., particles with sub μm dimensions) is based on their surface plasmon modes (see Sect. 2.2.2). A metal nanoparticle can in some sense be seen as a resonator for surface plasmons and, like any (moderately damped) resonator, if excited ...
