title: Imaging visible light using anisotropic metamaterial slab lens.
abstract: It has been shown that an anisotropic metamaterial made of nanowire array can realize negative refraction of light even without a negative phase index of refraction. Such non-resonant bulk material can be fabricated by bottom-up electrochemical method. Using this material, we were able to achieve lensing action with micron-thick slab and demonstrate imaging of a slit object. The details of the focused light beam in 3-dimensional space have been mapped with near field scanning optical microscope (NSOM).
