This thesis describes several ways in which to manipulate ultrasound by means of Fabry-Perot resonant acoustic metamaterials (AMMs), Fresnel-type lenses and phononic crystals (PCs). These can be used to obtain properties such as sound focussing or sub-wavelength imaging in water, which are highly desirable characteristics in several applications such as biomedical imaging and flaw detection. The metamaterials and the other structures described in this thesis were mostly additively manufactured, with the further aim of validating the different layer-bylayer fabrication methods to build them. Experiments were conducted in a water tank and results were compared to numerical predictions obtained through Finite Element Modelling (FEM). Sever...
