Abstract

This article is devoted to the theory of the converse magnetoelectric (CME) effect for the longitudinal, bending, longitudinal-shear, and torsional resonance modes and its quasi-static regime. In contrast to the direct ME effect (DME), these issues have not been studied in sufficient detail in the literature. However, in a number of cases, in particular in the study of low-frequency ME antennas, the results obtained are of interest. Detailed calculations with examples were carried out for the longitudinal mode on the symmetric and asymmetric structures based on Metglas/PZT (LN); the bending mode was considered for the asymmetric free structure and structure with rigidly fixed left-end Metglas/PZT (LN); the longitudinal-shear and torsional modes were investigated for the symmetric and asymmetric free structures based on Metglas/GaAs. For the identification of the torsion mode, it was suggested to perform an experiment on the ME structure based on Metglas/bimorphic LN. All calculation results are presented in the form of graphs for the CME coefficients.

摘要

本文致力于研究纵向、弯曲、纵向剪切和扭转共振模式下的逆磁电（CME）效应理论及其准静态状态。与直接磁电效应（DME）不同，这些问题在文献中尚未得到足够详细的研究。然而，在许多情况下，特别是在低频磁电天线的研究中，所获得的结果具有一定的意义。基于Metglas/PZT（LN）对对称和非对称结构的纵向模式进行了详细的实例计算；对非对称自由结构以及左端Metglas/PZT（LN）刚性固定的结构考虑了弯曲模式；基于Metglas/GaAs对对称和非对称自由结构研究了纵向剪切和扭转模式。为了识别扭转模式，建议在基于Metglas/双压电晶片LN的磁电结构上进行实验。所有计算结果均以CME系数的图表形式呈现。
