Two-dimensional imaging by far-field superlens at visible wavelengths

Nano Lett. 2007 Nov;7(11):3360-5. doi: 10.1021/nl0716449. Epub 2007 Oct 5.

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.
