Abstract
In this chapter, the characteristics of acoustic metamaterials in manipulation of elastodynamic and acoustic waves is explained. Acoustic bandgaps are introduced and the role of topology optimisation for enhancing the bandgap efficiency of PhCrs is discussed. Application of PhPs in manipulation of guided waves in thin-walled structures for design of low loss vibroacoustic devices and structural health monitoring is explained. Finally, the research scope targeting topology optimisation of PhPs is introduced.
