Abstract:
We report that two-dimensional (2D) sub-diffraction-limited images can be theoretically reconstructed by a new metamaterial far-field superlens. The metamaterial far-field superlens, composed of a metal-dielectric multilayer and a one-dimensional (1D) subwavelength grating, can work over a broad range of visible wavelengths intrinsically. The imaging principle and the reconstruction process are described in detail. The 2D sub-diffraction-limited imaging ability enables more applications of the far-field superlens in optical nanoimaging and sensing.
