Theory of Surface Acoustic Wave Devices for Particle Manipulation

In this chapter, we present the theory of surface acoustic waves (SAWs). The equations describing SAWs are derived for a solid–vacuum interface. Generalisations are made about wave behaviour at solid–solid and solid–fluid interfaces and techniques for SAW generation are discussed. This background provides a basis for the discussion of microfluidic applications of SAW technology in Chapter 15.
