| Abstract: | Transformation acoustics opens a new avenue towards the modeling and simulation of acoustic cloaks. The design of acoustic cloaks is based on the property of Helmoltz equations to be invariant under a geometric transformation. In this paper, a spherical shell cloak made of auxetic material (material with negative Poisson’s ratio) is discussed. The original domain consists of spheres made from conventional foam with positive Poisson’s ratio. The spatial compression leads to an equivalent domain filled with auxetic material. |
