Paper Abstract

Fundamental Fourier optics is applied to metallic near-field superlens, whose transfer function is computed with the transfer matrix, the Surface Plasmon Polariton (SPP) resonance and the SPP waveguide theory. However, when the object nano-structure consists of feature nano-slits and nano-holes etc, which are as the basic object elements to scatter the light, especially when the objects are metal, the electrical dipoles are induced at the nano-slits and nano-holes by the illuminating light, the space invariance condition can be not respected within the dimension of the nano-meter scale objects, so that the point spread function becomes approximate and the superlens is usually characterized by the image of a two nano-slit pattern. The superlens is designed and optimized based on the transfer function. Improvement in the transfer function can improve significantly the image quality. The real image of the near-field superlens can be computed with numerical simulation using the FDTD method.
