Abstract

Recently, the near-field superlens (NFSL) has been used as a suitable material for the super-resolution beyond the diffraction limits. These NFSL materials in the nature, such as metals and polar dielectric crystals, usually have intrinsic absorption loss in the Re(ε) < 0 region. In the imaging system, such absorption loss decreases the retardation effects by softening the singularity of transmission resonances, but it does not remove the phase singularity that severely deteriorates the ideal image restoration. Because of this problem, TiO2 thin film cannot still have sufficient band of spatial frequency for the super-resolution in the mid IR regime. In this research, we report the achievement superresolution in TiO₂ NFSL by elimination of the phase singularity based on the phase correction method.
