    "summary": "Lee and colleagues described a curved layered optical hyperlens and imaged closely spaced test features with a conventional far-field microscope. In the reported 365-nanometre illumination experiment, the reconstructed image resolved a line-pair separation down to approximately 125 nanometres. An anisotropic effective-medium model and electromagnetic simulation explained how the structure magnifies fine spatial information before ordinary optical detection.",

Magnification was only along one direction and the reported transmission was about an order of magnitude below the simulation, affecting exposure time.
