We show that engineered diffraction gratings can considerably simplify the design of acoustic ground
cloaking devices. Acoustic reflecting gratings are designed in such a way that all the incident energy is
channeled toward the diffracted mode traveling in the direction opposite the direction of the incident field
(retroreflection effect), and this effect is used to cloak an object placed over an acoustically rigid surface.
Axisymmetric gratings consisting of rigid surfaces with just one groove per unit cell are used to design
thin acoustic carpet cloaks. Finally, full-wave numerical simulations are performed and a conical carpet
cloak is experimentally tested, showing an excellent scattering-cancellation effect. [-]
