Previous papers have reported equivalent circuit analysis and circuit models of longitudinal or transverse type magnetoelectric (ME) composites. In this paper, a hybrid Mason's equivalent circuit model is developed for shear piezomagnetic/shear piezoelectric (S-S) mode resonance bilayer composites structure. A high-quality factor (Q-factor) LiNbO3/Metglas shear mode ME structure is then investigated by theoretical modeling of both piezomagnetic and piezoelectric layers. A hybrid shear mode equivalent circuit is presented by introducing the concept of Mason's equivalent circuit model for the piezomagnetic layer. The modeling results reveal the potential of S-S model ME composites with high Q- factor to achieve an exceptional high ME coefficient, e.g., the bilayer structure at resonance of RF frequency (>MHz) exhibits a ME coefficient of 175,000 V/cmOe.
