Reactive near field region
Webnear-field for proper data acquisition. The antenna has a reactive near-field from 0 to λ with a fairly flat field distribution, where objects in this region can possibly cause unwanted coupling to the antenna. As such, near-field systems cannot measure inside this region due to the unknown coupling effects to an AUT.

WebLegend Y - youth athletes welcome O - open athletes welcome M - masters athletes welcome WebThe term reactive near field arises from the fact that for a non-resonant antenna such as an electrically-small dipole, reactive power circulates between the reactive near field and the …
WebThis distance provides the limit between the near and far field. What is the reactive near field? The reactive near field is the region where the fields are reactive i.e the E and H fields are out of phase by 90 degrees to each other. For propagating or radiating fields, the fields must be orthogonal to each other but in phase. Webreactive near-field region, the radiating near-field region, and the far-field region. Major effort was directed towards determining the aperture distribution in the reactive near field in order to utilize this information in determining the …
WebIn this sense, it can be important to distinguish between the two types of fields and which is dominant. Wireless power transfer technology such as magnetic induction and magnetic resonance are based on transferring energy using the magnetic field component in the reactive near-field region.
