Metamaterials are materials designed by man with static or dynamic properties inaccessible to natural materials. Among them, phononic crystals consist of a periodic assembly of two or more materials, and are mainly used for the design of waveguiding

Phononic Crystal (PnC) is a periodic artificial crystal made of two different elastic constant materials enabling the acoustic/elastic wave manipulation. Its acoustic properties, such as the existence of phononic band gap (PnBg), which is defined as

In this thesis, a study of periodic microstructures and their applications to optical modulation by acoustical waves is presented. More specifically, it deals with opto-mechanical coupling in phoXonic crystal cavities. This study shows how the pertur

Surface acoustic wave resonators can be used as sensors for temperature and strain monitoring. The idea is to take advantage of the variation in frequency of the resonators that depends on the measured quantity. Currently, the technology used, based
