Abstract Magnetoelectric (ME) materials can realize the conversions between electric and magnetic energy. Different from the previous studies, the electromagnetic (EM) radiation of ME materials has been adequately considered in this work. The electrical energy input can be converted into the dynamic magnetization oscillation by converse magnetoelectric (CME) effect. The antennas operate at their acoustic resonance frequency, which provides a new idea for antenna miniaturization. We analyze the CME effect and EM radiation from a vibrating ME laminated composite. The results show that the ME heterostructure resembles an ideal magnetic dipole in terms of radiating EM waves. This structure reduces the antenna size by several orders of magnitude, suggesting vast superiority of controlling magnetizations to generate EM radiation at a micro-scale.

磁致伸缩/压电层压复合材料诱发的电磁辐射建模

摘要 磁电（ME）材料可以实现电能和磁能的转换。与以往的研究不同，本工作充分考虑了 ME 材料的电磁 (EM) 辐射。电能输入可以通过逆磁电（CME）效应转换为动态磁化振荡。天线以其声共振频率工作，这为天线小型化提供了新思路。我们分析了振动 ME 层压复合材料的 CME 效应和 EM 辐射。结果表明，就辐射电磁波而言，ME异质结构类似于理想的磁偶极子。这种结构将天线尺寸减小了几个数量级，表明在控制磁化以在微尺度上产生电磁辐射方面具有巨大的优势。
