Far-field super-resolution imaging with a planar hyperbolic metamaterial lens beyond the Fabry-Perot resonance condition

摘要

We demonstrate achieving the far-field super-resolution imaging can berealized by using a planar hyperbolic metamaterial lens (PHML), beyond theFabry-Perot resonance condition. Although the thickness of the PHML is muchlarger than wavelength, the PHML not only can transmit radiative waves andevanescent waves with high transmission, but also can collect all the waves inthe image region with the amplitudes of them being the same order of magnitude.We present a design for a PHML to realize the far-field super-resolutionimaging, with the distance between the sources and the images 10 times largerthan wavelength. We show the superresolution of our PHML is robust againstlosses, and the PHML can be fabricated by periodic stacking of metal anddielectric layers.
