A specific feature of the acoustoelectric scattering of the nonuniform surface acoustic wave (SAW) beams by the straight metal strips placed on the piezoelectric substrates is discussed. A closed-form solution is obtained to describe the influence of diffraction on the reflective delay line with finite aperture. The found results allow us to develop the fast simulation and synthesis tool that can be applied to evaluate and compensate for the diffraction effect in SAW tags of arbitrary architectures. Efficiency of the proposed approach is illustrated by example of SAW tag synthesized on 128 degrees -LiNbO(3).
本文讨论了在压电衬底上放置直金属条时非均匀表面声波(SAW)束的声电散射的一个特定特征。获得了一个封闭形式的解,用于描述有限孔径反射延迟线中衍射的影响。所得到的结果允许我们开发快速模拟和综合工具,可用于评估和补偿任意结构的 SAW 标签中的衍射效应。通过在 128 度-LiNbO(3)上合成的 SAW 标签的示例说明了所提出方法的效率。
