Cloak Changing with Background

摘要：

Coordinate transformation approach has previously been used for designing cloak which can shield an interior region in a homogeneous medium. In this letter, we consider the case where the background is no longer a homogeneous medium and determine the relative constitutive parameters of the cloak according to the multilayered background. We propose the parameters of cylindrical cloak structures working in multilayered media and the scheme of specifying these parameters could also be applied to the design of cloak in arbitrary isotropic background. The theoretical analysis based on coordinate transformation is given and numerical simulations are performed to illustrate these properties. The simulation results show that the cloaking with the proposed parameters performs well in these inhomogeneous background medium. Potential applications are also discussed.
