Materials with a negative refractive index can form super-resolution planar lenses, sub-surface cameras or compact resonators which are otherwise impossible to realize. MRSEC researchers have predicted for the first time a tunable negative-index material with low loss, using liquid crystals, whose operating wavelength can be changed by controlling the liquid crystal orientation.
