Abstract

The coupling effect in a near-field object-superlens system has been studied, where the object is a silver cylinder and the superlens is a silver slab. A semi-analytical formulation has been established to study the system with and without the coupling effect. The analysis shows that the coupling effect significantly changes the field distributions of both the object and the image, leading to the conclusion that such a system must be designed and analyzed as a whole. Our study also suggests that it is possible to design a superlens system with mismatched permittivities.
