The article discusses the physical foundations of the application of the linear magnetoelectric (ME) effect in composites for devices in the low-frequency range, including the electromechanical resonance (EMR) region. The main theoretical expressions for the ME voltage coefficients in the case of a symmetric and asymmetric composite structure in the quasi-static and resonant modes are given. The area of EMR considered here includes longitudinal, bending, longitudinal shear, and torsional modes. Explanations are given for finding the main resonant frequencies of the modes under study. Comparison of theory and experimental results for some composites is given.
本文讨论了线性磁电(ME)效应在低频范围内用于器件的复合材料中的应用的物理基础,包括机电共振(EMR)区域。给出了准静态和谐振模式下对称和不对称复合结构情况下ME电压系数的主要理论表达式。这里考虑的EMR区域包括纵向、弯曲、纵向剪切和扭转模式。对确定所研究模式的主要共振频率进行了解释。给出了一些复合材料的理论与实验结果的比较。
