Abstract :
This paper is dedicated to the analysis of determination of volume and anisotropy field distributions using the complex transverse susceptibility (TS). We consider in our study two-dimensional arrays of particles as magnetic patterned media. It is shown that the amplitude of excitatory ac field and the interactions between particles play an important role
