    "abstract": "Near-field enhancement and sub-wavelength imaging properties of a system\ncomprising a coupled pair of two-dimensional arrays of resonant nanospheres are\nstudied. The concept of using two coupled material sheets possessing surface\nmode resonances for evanescent field enhancement is already well established in\nthe microwave region. This paper shows that the same principles can be applied\nalso in the optical region, where the performance of the resonant sheets can be\nrealized with the use of metallic nanoparticles. In this paper we present\ndesign of such structures and study the electric field distributions in the\nimage plane of such superlens.",
