Abstract

FDTD simulation of a Surface Acoustic Wave (SAW) RFID tag is presented. The simulated tag consists of a single-electrode Inter-digital Transducer (IDT) with ten electrodes and three single-electrode reflectors, printed on the surface of a 128°YX Lithium Niobate (LiNbO3) piezoelectric substrate. FDTD modeling is done considering the multyphisics nature of the problem, by combining the electromagnetic and the elastodynamics theory in order to obtain the piezoelectric governing equations. Simulation results allow determining the time-position and insertion loss of SAW echoes, which enables the determination of the ID code stored in the tag.
SAW RFID标签的时域有限差分仿真
对表面声波(SAW) RFID标签进行时域有限差分仿真。模拟标签由一个带有十个电极的单电极数字传感器(IDT)和三个单电极反射器组成,印刷在128°YX铌酸锂(LiNbO3)压电衬底表面。考虑到问题的多物理特性,结合电磁学理论和弹性动力学理论进行时域有限差分建模,得到压电控制方程。仿真结果可以确定声呐回波的时间位置和插入损耗,从而可以确定存储在标签中的ID代码。
