dc.description.abstractA tunable near-field superlens (NFSL) from metal-dielectric composites has advantages over that one from bulk metal. In this paper, we realize the tunable NFSL by tuning the shape of granular inclusions. It is found that the tunability of NFSL can be enhanced by adjusting both the volume fraction and the particles' shape. Moreover, we also find that when the shape of particles is not spherical, the percolation threshold is low, resulting in a wider wavelength range of superlens. The imaging quality and resolution can be enhanced not only by changing the particles' shape but also by using a multilayered structure with alternate metal-dielectric composites and host medium. © 2007 The American Physical Society.
