Shifting media induced super-resolution imaging

Abstract

In this paper, we propose a novel method to achieve super-resolution imaging by utilizing shifting media based on the transformation optics theory. According to the effective medium theory, the homogenous but anisotropic shifting media can be simply replaced by only two kinds of homogenous and isotropic materials in an alternating layered structure. In addition, another scheme of the symmetrical trapezoidal shifting media shells with layered isotropic materials is proposed to realize the super-resolution imaging. Finite element simulations have been performed to prove these ideas.
