Abstract: The article is devoted to the theoretical study of the magnetoelectric interaction in the ferrite-piezoelectric-substrate layered structure in the mode of frequency coincidence of ferromagnetic resonance in ferrite and one of the modes of electromechanical resonance of piezoelectric. The results of calculating the magnetoelectric coefficient in the region of magnetoacoustic resonance in the structure of YIG / lithium niobate / silicon in the thickness-longitudinal mode are presented. At a resonance frequency of 1,7 GHz, the magnetoelectric coefficient is 32 V/(cm $\cdot$ Oe). The obtained results can be used in setting up an experimental study.

Keywords: magnetoelectric effect, electromechanical resonance, ferromagnetic resonance, magnetoacoustic resonance, yttrium iron garnet, lithium niobate, layered magnetoelectric structure.
