A super-resolution imaging method for the deep sub-wavelength structure has been proposed, which is achieved by controlling the propagating direction of the evanescent components of the incident field through a one-dimensional metamaterial structure (ODMS) with an anisotropic dielectric permittivity. We provide the mechanism of this kind of super-resolution imaging method in detail and discuss some factors influencing image quality. A two-dimensional finite element method (FEM) has been used to verify the imaging mechanism. Furthermore, the same sub-diffraction limited image could be obtained at different incident wavelengths at the far side of the imaging structure with different working distances.
