“…In recent years, research interest in the CME effect in the low-frequency region has increased. This is due to the great interest in the design of magnetic field sensors [ 16 , 17 , 18 ] and low-frequency ME antennas [ 19 , 20 , 21 , 22 ] and the possibility of their use in spintronics [ 23 , 24 , 25 , 26 , 27 , 28 ] and ME memory devices [ 29 , 30 , 31 ]. The purpose of this article is a brief analysis of the works on the CME effect and to obtain expressions for CME coefficients for the low-frequency region, including the electromechanical resonance (EMR) modes: longitudinal, bending, longitudinal-shear, and torsional.…”

“…The ME resonant disk structure with a diameter of 70 μm and a thickness of 1 μm with SiO 2 /Cr/Au/AlN/Cr/Au/FeGaB-stacked layers was prepared on a 300 μm silicon wafer and showed a giant ME coefficient of 2.928 kV/cm/Oe in resonance at 224.1 kHz. The article by [ 22 ] is devoted to assessing the CME effect within the framework of a two-dimensional multifield communication model for an acoustically controlled antenna. To compare the results obtained in our paper, it is necessary to clarify the details of the calculation in [ 22 ].…”

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.

“…The stress and strain were transferred to the magnetostrictive phase, and subsequently, the magnetic field was generated based on the converse magnetostrictive effect [ 34 ]. This combined phenomenon is referred to as the converse magneto-electric effect [ 35 , 36 ]. As observed in the impedance measurement of Figure 2 , an impedance of 478e −j1.2 for the ME transmitter antenna at 22.47 kHz resulted in an input power of 2.09 mW.…”

VLF magneto-electric (ME) antennas have gained attention for their compact size and high radiation efficiency in lossy conductive environments. However, the need for a large DC magnetic field bias presents challenges for miniaturization, limiting portability. This study introduces a self-biased ME antenna with an asymmetric design using two magneto materials, inducing a magnetization grading effect that reduces the resonant frequency during bending. Operating principles are explored, and performance parameters, including the radiation mechanism, intensity and driving power, are experimentally assessed. Leveraging its excellent direct and converse magneto-electric effect, the antenna proves adept at serving as both a transmitter and a receiver. The results indicate that, at 2.09 mW and a frequency of 24.47 kHz, the antenna has the potential to achieve a 2.44 pT magnetic flux density at a 3 m distance. A custom modulation–demodulation circuit is employed, applying 2ASK and 2PSK to validate communication capability at baseband signals of 10 Hz and 100 Hz. This approach offers a practical strategy for the lightweight and compact design of VLF communication systems.
