Based on coordinate transformation incorporated with conformal mapping approach, a sub-wavelength imaging device with magnification, called planar hyperlens is designed, capable of realizing far-field plane-to-plane imaging beyond the diffraction limit. The possible implementation method is proposed by using effective anisotropic metamaterial formed by alternating metallic and dielectric thin layers. The magnification performance of the designed multi-layer lensing structure is numerically simulated to confirm our theoretical analysis. (C) 2008 Optical Society of America
