Transformation optics provides a new design methodology allowing unprecedented manipulation of light propagation. Traditionally, optical elements only involve stretching or compressing the optical space in one direction whereas the remaining dimensions are unaltered. However, space can be modified in all dimensions simultaneously so that the additional degrees of freedom provided by transformation optics can be used to imprint different elements into a single optical device.
