Abstract

The magnetoelectric (ME) effect in composite materials results from the combination of the magnetostrictive effect and the piezoelectric effect via elastic interaction. This work focuses on the modeling of multilayer structures under dynamic excitation. The calculated ME coefficient versus frequency shows the enhancement of the ME effect at mechanical resonance in accordance with experimental measurements. The impact of electric conductivity is investigated. Applications on the ME sensor and tunable inductor are proposed.
