Abstract :
The process of inverse filtering in the frequency domain was applied to solve the inverse problem of determining the magnetic bidimensional source from a bidimensional magnetic field mapping. This technique is used to image the magnetic moment distribution induced on a planar sample when an external magnetic ac field is applied.
