Abstract :
Magnetoelectric (ME) effect in composite materials results of magnetostrictive effect and piezoelectric effect via elastic interaction. This work focuses on the modeling of a bilayer structure under dynamic excitation. The calculated ME coefficient versus frequency shows the enhancement of ME effect at resonance in accordance with experimental measurements. The impact of the electric conductivity is also investigated.
