论文摘要
我们得出了一个分析模型，用于由由压电 - 磁通性双层组成的磁电膜大量声音谐振器中的电源传递模型。该模型通过有效的频率依赖性刚度常数描述了对弹性动力学的动态磁静脉影响。这允许在将这种谐振器视为磁传感器时，可以计算谐振器中的磁和弹性功率吸收及其能效。然后，将模型应用于由压电发明和磁缩写的COFEB，NI或Terfenol-D层组成的示例系统。
We derive an analytical model for the power transfer in a magnetoelectric film bulk acoustic resonator consisting of a piezoelectric--magnetostrictive bilayer. The model describes the dynamic magnetostrictive influence on the elastodynamics via an effective frequency-dependent stiffness constant. This allows for the calculation of both the magnetic and elastic power absorption in the resonator as well as of its energy efficiency when such a resonator is considered as a magnetic transducer. The model is then applied to example systems consisting of piezoelectric ScAlN and magnetostrictive CoFeB, Ni, or Terfenol-D layers.
