Research on Acoustically Actuated Magnetoelectric Transceivers via Equivalent Circuit Model with Electromagnetic Duality

Magnetostrictive/piezoelectric composite structures with novel magneto-electric transduction mechanism have been used to design portable antennas. To simplify the analysis of the multi-field coupling within the magnetoelectric (ME) composites, a lumped equivalent circuit model with electromagnetic duality is proposed in this work. Based on the model, the transceiver performances of ME antennas operating in dual mechanical resonance modes are studied and the lumped parameters are extracted to calculate the transmission characteristics of the ME antenna pair. Both the calculation and experimental results suggest that the transmission performance can be significantly improved by the inductor matching of the ME receiver.
