Abstract

En 中文

It is demonstrated that a system of two interfacing hyperbolic metamaterials may be used for direct sub wavelength imaging in the visible range. The proposed configuration consists of two anisotropic photonic crystals: a multilayered metal-dielectric structure and an adjoined wired structure. The results of analytical calculations and numerical modeling show that the light emitted by a dipole placed on the top of the multilayered structure propagates within a narrow cone along the direction n, where Re S (co, n) = 0. Owing to impedance matching and negative refraction at the interface, a bright image with a maximum transverse size of approximately 50 nm is focused in the wired structure at the wavelength A = 670 nm.
