Employing rigorous electromagnetic theory we show that near-field imaging of point-like objects with subwavelength resolution is achieveable with nanoslab superlenses. For a metallic lens the resolution is ∼ λ /5, whereas for a metamaterial lens λ /10 is obtained. We also illustrate how the near-field interactions among the objects and the lens affect the imaging.
