Abstract

The imaging properties of the single-layer metallic superlens are studied systematically. We computed the impulse response and the transfer function of the lens which are critical for understanding the imaging performance of this superlens and for possible improvements in the future. Furthermore, we relate the single layer superlens structure to the well known surface plasmon polariton (SPP) waveguide, and find out that the metal slab superlens is a particular type of SPP waveguide, where the field distribution is mainly determined by the long- and short-range modes. We show that the excitation of the long-range mode causes large sidelobes in the impulse response. We propose to improve the imaging performances of the superlens by designing a structure for which the long-range mode is cutoff.
