Abstract

The resolution of imaging is limited by the missing of high-frequencies information. However, these information can be amplified by the metamaterial or surface plasmon polaritons. A silver film having sub-wavelength slit sandwiched between a front grating similar to Fresnel zone plate and back grating, are proposed to realize super-resolution imaging. We choose a wavelength in which the surface plasmon polaritons can be excited and negative refraction imaging can be implemented synchronously. By the numerical simulations, a fine image can be actualized within several wavelengths distance from the silver film.
