Abstract

Ag slab near-field superlens (NFSL) has been much attractive issue due to their application of nano-imaging by the resolution beyond the diffraction limits. Although it has the advantages as sub-wavelength imaging tools, Ag NFSL always suffers from image blurring due to the intrinsic absorption loss, which prevent the ideal reconstruction of nanoimaging. In this research, through the analysis of focal property using the FDTD, we recognized that the impedance mismatched Ag NFSL is useful as the phase corrected optical components in the near-field. As a result, the significant enhanced of visibility, depth of field, and resolving capability is achieved in the mismatched Ag NFSL imaging system.
