In this paper we propose an original simple approach to the description of asymmetric plated heterogeneous magnetoelectric structures under external electric and magnetic fields. The existence of the considerable resonance enhancement of magnetostrictive, piezoelectric, dielectric and magnetic properties is found. The important role of the electric and magnetic interconnection influence on the effective properties is carefully analyzed. Direct and converse magnetoelectric susceptibilities are derived and compared and the difference between them is discussed. The magnetoelectric part of the results obtained for direct magnetoelectricity is compared with experiment. The comparison between plated structures and composites is done. The results are applicable far from the bending resonance frequencies, which are calculated and analyzed here. All these would be favorable for practical magnetoelectric, piezoelectric, magnetostrictive, magnetic, and dielectric resonance applications.
