In this paper, number 17 of the thematic tutorial series "Acoustofluidics-exploiting ultrasonic standing waves, forces and acoustic streaming in microfluidic systems for cell and particle manipulation", we present the theory of surface acoustic waves (SAWs) and some related microfluidic applications. The equations describing SAWs are derived for a solid-vacuum interface before generalisations are made about solid-solid and solid-fluid interfaces. Techniques for SAW generation are discussed before an overview of applications is presented.
在本专题教程系列“声流学——利用微流控系统中的超声驻波、力和声流对细胞和颗粒进行操控”的第 17 篇中，我们介绍了表面声波（SAW）的理论及其在微流控方面的一些相关应用。本文首先推导了在固-真空界面中描述 SAW 的方程，然后将其推广到固-固和固-液界面。在介绍 SAW 的产生技术之前，先对其应用进行了概述。
