Transformation optics shapes metamaterials ** Transformation optics shapes metamaterials. ** Professor Sir John Pendry, Centre for Plasmonics & Metamaterials, Imperial College London Metamaterials offer a huge range of new electromagnetic properties: negative refraction, spatial inhomogeneity to name only two. To exploit the possibilities offered in this new world we need a new design tool. Maxwell´s equations are exact at the classical level but lack transparency; Snell´s law is elegantly visual, an aid to the imagination, but fails to account for many vital aspects of electromagnetism. Transformation optics retains an intuitive appeal, replacing the rays of Snell´s law with the field lines of Maxwell whose equations is represents exactly.
