Abstract
A new concept is introduced to extract the essential and distinct characteristics of the magnetic field distributions. A key idea is to calculate an eigen pattern, which can represent the characteristics of magnetic fields independent of their resolutions and space positions. The eigen pattern of a magnetic field distribution is obtained by projecting the three orthogonal magnetic field vector components at each of the space coordinates onto the x-, y- and z-magnetic field components coordinate system. Thereby, this projection is possible to remove the space coordinate information, and extract the essential vector characteristics of the target magnetic field distribution. As a result, we have succeeded in identifying and recovering the magnetic field distributions with high resolution.
