In this paper, we use COMSOL, finite element software, to compute the magnetodielectric effect in a multiferroic structure based on a {ferromagnetic /piezoelectric} multi-layer. We also investigate the potential tunable applications of such structures at microwave frequencies. In a first part, we present the piezoelectric and magnetostrictive equations which were then used to develop the global magnetodielectric model. To validate the magnetostrictive model, results of simulation were then compared to published experimental results. The global magnetodielectric model was also validated using microwave measurements of a FeCoB /PVDF / FeCoB tri-layer structure. Finally, we associated magnetodielectric and RF models to investigate the potential of different structures to tunable microwave applications.
