    "abstract": "We analyze the performance of a planar lens based on realistic negative index\nmaterial in a generalized geometry. We demonstrate that the conventional\nsuperlens design (where the lens is centered between the object and the image)\nis not optimal from the resolution point-of-view, develop an analytical\nexpression for the resolution limit of a generalized lens, use it to find the\noptimum lens configuration, and calculate the maximum absorption practical\nnearfield superlenses may have. We demonstrate that in contrast to the\nconventional superlens picture, planar imaging is typically accompanied by\nexcitation of surface waves at both interfaces of the lens.",
