DESCRIPTION:Friday\, December 11th\, 12:00\, ICFO's AuditoriumJOHN PENDRYIm
 perial College London $$John Pendry has made seminal contributions to surf
 ace science\, disordered systems and photonics. His most recent work has i
 ntroduced a new class of materials\, metamaterials\, whose electromagnetic
  properties depend on their internal structure rather than their chemical 
 constitution. Pendry discovered that a ‘perfect lens’ manufactured fro
 m negatively refracting material would circumvent Abbé’s diffraction li
 mit to spatial resolution\, which has stood for more than a century. His m
 ost recent innovation of ‘transformation optics’ gives the metamateria
 l specifications required to rearrange electromagnetic field configuration
 s at will\, by representing the field distortions as a warping of the spac
 e in which they exist. In its simplest form the theory shows how we can di
 rect field lines around a given obstacle and thus provide a ‘cloak of in
 visibility’\, which was first realised at Duke in 2006
