• Field: Optics, masers and lasers
• Keywords: sub-wavelength resolution; radiation outlet; optical imaging; Maxwell's fish eye
• Description: The resolution of lenses is normally limited by the wave nature of light. Imaging with perfect resolution was believed to rely on negative refraction, but here we present experimental evidence for subwavelength imaging with positive refraction.
