Phononic crystals and acoustic metamaterials
are periodic structures whose effective properties can be
tailored at will to achieve extreme control on wave propagation. Their refractive index is obtained from the homogenization of the infinite periodic system, but it is possible
to locally change the properties of a finite crystal in such
a way that it results in an effective gradient of the refractive index. In such case the propagation of waves can be
accurately described by means of ray theory, and different refractive devices can be designed in the framework of
wave propagation in inhomogeneous media. In this paper
we review the different devices that have been studied for
the control of both bulk and guided acoustic waves based
on graded phononic crystals. [-]
