基于粘接层参数优化的磁电天线性能调控
Performance regulation of magnetoelectric antennas based on optimization of bonding layer parameters
摘要
Abstract
Multiferroic magnetoelectric materials,with their magnetoelectric effect,have demonstrated significant application value in the field of new magnetoelectric devices.Layered composite structure is an effective approach to achieving magnetoelectric coupling,but the material parameters and geometric characteristics of their bonding layers can affect the magnetoelectric coupling coefficient,resonant frequency,and transmission performance of the antenna.Aiming at the layered magnetoelectric antenna composed of piezoelectric ceramics(PZT-5H)and magnetostrictive materials(Metglas),the intrinsic correlation between the characteristics of the bonding layer and the performance of the magnetoelectric antenna was revealed by adjusting the thickness and hardness of the epoxy resin bonding layer,combining theoretical analysis with experimental verification.The results show that the thickness variation of the bonding layer causes the magnetoelectric coupling coefficient of the antenna to increase first and then decrease(reaching the maximum of 122.69 V·(cm·Oe)-1 at 0.035 mm),and the resonant frequency decreases as the thickness increases.Furthermore,increasing the hardness of the epoxy resin can significantly enhance the mechanical transmission performance of the antenna,thereby improving its receiving and radiating capabilities.When the thickness of the bonding layer was 0.035 mm,by using an epoxy resin with a hardness of 82D as the bonding layer,the receiving and radiation performance were respectively enhanced by 38.7％ and 8.2％ compared to when the hardness was 35D.This verified the feasibility of the scheme.In conclusion,the parameters of the bonding layer of the magnetoelectric antenna were optimized and its core performance was precisely regulated in this paper,which provides a theoretical basis and a technical approach for achieving high-performance magnetoelectric antenna devices.关键词
