Optical lenses are pervasive in various areas of sciences and technologies. It is well-known that the resolving power of a lens and thus optical systems is limited by the diffraction of light. Recently, various plasmonics and metamaterials based superlenses have been emerging to achieve super resolution. Here, we show that the phase compensated negative refraction lenses perform as "Janus Lenses", i.e. either converging lenses or diverging lenses depending on the illumination directions…
