Scattering camouflage and manipulation using metasurfaces

Abstract : In this contribution, we propose the use of metasurfaces not only to cloak an object but also to change its scattering response in view of camouflage and scattering manipulation applications. We present the analytical formulation for the case of a cylindrical object with the goal of deriving the surface impedance of the surrounding metasurface to make the object appearing as it were either larger or thinner. We find that not all the camouflage cases can be achieved by using only passive metasurfaces and active components may be required. The analytical and numerical results are discussed, in view of possible actual applications.
