  1. Pendry, JB; Smith, DR, THE QUEST for the superlens, Scientific American, vol. 295 no. 1 (2006), pp. 60-67 .

    The superlens, made from metamaterials with bizarre, controversial optical properties have the capacity to produce images that include details finer than the wavelength of light that is used. When an electromagnetic wave travels through a material, the electrons within the material's atoms or molecules experience a force and move in response to it. This motion uses up some some of the wave's energy which affects the properties of the wave and the way in which it travels. Resonance, which is the tendency to oscillate at a particular frequency, is the key to achieving a negative response and is introduced artificially in a metamaterial by building small circuits designed to mimic the magnetic or electrical response of a material. The demonstration of superlensing id the latest of many predictions for negative-index materials to be realized which is an indication of the rapid progress that has occurred in the emerging field.
