摘要
An approximation approach is proposed for realizing an arbitrarily shaped acoustic cloak. Based on the effective medium theory, the designed cloak is a discrete layered structure using homogeneous isotropic materials. The performance of the cloak is simulated, and the results demonstrate that the cloak possesses properties of low-reflection outside the cloak and wavefront-bending in the cloak shell. This work proves the feasibility of realizing an arbitrarily shaped acoustic cloak using normal materials.
