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. WebThe Near Field is further divided into Reactive Near Field and Radiative Near Field. We know that in the Far Field the E-field, H-field and directional of propagation are all perpendicular to each other and E-field and H-field are in phase. The impedance of free space (given as ratio of E-field and H-field) in this region is equal to 377 ohms ...

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.
