WebFraunhofer diffraction is relevant when considering the far field, i.e., diffraction patterns far away from the refracting structure; this regime is characterized by values of the Fresnel number well below 1. On the other hand, the concept of Fresnel diffraction with large Fresnel numbers can be applied to cases where the near field is relevant. WebFor antennas shorter than half of the wavelength of the radiation they emit (i.e., electromagnetically "short" antennas), the far and near regional boundaries are measured in terms of a simple ratio of the distance r from the radiating source to the wavelength λ of the radiation. For such an antenna, the near field is the region within a radius r ≪ λ, while the …
