Preface
Phononic crystals (PnCs) are novel synthetic periodic materials for controlling and manipulating the propagation of elastic (or acoustic) waves. The periodic nature of PnCs gives them novel properties that cannot be found in bulk materials. For example, PnCs can exhibit acoustic (or phononic) bandgaps, which are frequency ranges in which the propagation of acoustic waves inside the PnC is prohibited. The addition of defects to a perfect PnC with a phononic bandgap allows for the design of devices like waveguides and cavities to control the propagation of acoustic waves inside the bandgap and to enable novel functionalities in a very compact structure. Imminent impact of PnCs is expected in the near future in applications like wireless communications, sensing, acoustic signal processing, and ultrasound imaging. Novel devices (such as acoustic filters, resonators, sources and lenses) with outstanding performance measures are being enabled by the use of PnCs. In addition, the use of these structures to form acoustic metamaterials can uncover novel effects like negative refraction, acoustic invisibility, or superlensing. This, in turn, can enable researchers to design functional structures with such performan
