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. WebApr 15, 2024 · The near-field region is the region next to the antenna and can further be classified into the reactive near-field and the radiative near-field. Near-field applications are used for close proximity tag reading and have a narrower beam to focus on specific areas. Reactive Near-Field: This region lies right next to the antenna. The region is ...
WebRe-radiated field. An electromagnetic field resulting from currents induced in a secondary, predominantly conducting, object by electromagnetic waves incident on that object from one or more primary radiating structures or antennas. Re-radiated fields are sometimes called "reflected" or more correctly "scattered fields." WebTypical reconstruction algorithms aim at obtaining the E - and H - field phasors in the far-field region. Nevertheless, the reactive near field is becoming increasingly important for …
WebThe treatment is limited to an isotropic scattering environment but can be extended to the non-isotropic case through the linear-system theoretic interpretation of plane-wave propagation. Numerical results show that evanescent waves have the significant potential to provide additional DoF and capacity in the reactive near-field region. WebMay 29, 2024 · 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 …
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 …
