论文标题：Acoustic Cloaks for Complex Backgrounds Media with Homogeneous Metamaterials

作者：朱建，陈天宁，梁庆宣，王小鹏，熊杰

摘要：The acoustic cloak, which can make an object hard to detect acoustically in a homogeneous background, has attracted great attention from researchers. We focus on the situation that the background is inhomogeneous medium in this paper. Through the transformation acoustics theory we derive the constitutive parameters of the arbitrary shapes cloaks working in complex media. And a unidirectional acoustic cloak for layered background is designed and realized with homogeneous metamaterials. The effective parameters of the cloak are determined by using the effective medium theory. Good cloaking performance showed that such a device could be physically realized with natural materials which will greatly promote the real applications of invisibility cloak in inhomogeneous backgrounds.
