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.
