Popis:	The theoretical investigation of the frequency dependence of the inverse magnetoelectric effect in piezomagnetostrictive rings in the region of radial resonances has been presented. The analytical expression for the coefficient of the inverse magnetoelectric conversion for ring-like samples with the axial polarization has been derived. It has been shown that the energy is redistributed between the modes depending on the structure geometry, which results in the formation of regions where some modes are absent while the amplitude of other ones increases. The voltage transfer coefficient, which can considerably exceed this parameter in the samples shaped as a continuous disc, has been theoretically predicted.
