主　　题：materials arbitrarily shaped 

摘      要：An approximation approach is proposed for realizing an arbitrarily shaped acoustic *** on the effective medium theory,the designed cloak is a discrete layered structure using homogeneous isotropic *** 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 *** work proves the feasibility of realizing an arbitrarily shaped acoustic cloak using normal materials.
