In this paper, we apply the coordinate transformation technique to the design of perfect lenses, which are able to perfectly reproduce an image on another surface. In particular, anisotropic metamaterials that magnify two-dimensional planar images beyond the diffraction limit are designed by the use of spheroidal coordinates. We show that the technique can be used to design transformation media that magnify images beyond the diffraction limit.
