SUMMARY:Metamaterials: new horizons in electromagnetism
DESCRIPTION:To book your free place at this year’s Schrödinger lecture\,
  please email Katie Weeks (k.weeks@imperial.ac.uk). A reception with demon
 strations of invisibility from the Department of Physics will follow the t
 alk.\nIn the last decade a new area of research has emerged as a result of
  our ability to produce materials with entirely novel electromagnetic prop
 erties. Known as metamaterials because they take us beyond the properties 
 of conventional materials\, they display remarkable effects not found in n
 ature\, such as negative refraction.\nSpurred on by these new opportunitie
 s\, theorists have produced exotic concepts that exploit the new materials
 : we can now specify how to make a lens whose resolution is limited not by
  the laws of nature but only by our ability to build to the stated specifi
 cations\; we can guide radiation along a trajectory\, avoiding objects and
  causing them to appear invisible\; we can design and manufacture material
 s that are active magnetically in the optical range.\nThere has been a tru
 ly amazing amount of innovation but more is yet to come. The field of meta
 materials is developing into a highly disruptive technology for a plethora
  of applications where control over light (or more generally electromagnet
 ic radiation) is crucial\, ­ amongst them telecommunications\, solar ener
 gy harvesting\, stealth\, biological imaging and sensing\, and medical dia
 gnostics.\nBiography\nJohn Pendry is a condensed matter theorist and has w
 orked at Imperial since 1981. He began his career in the Cavendish Laborat
 ory\, Cambridge\, followed by six years at the Daresbury Laboratory where 
 he headed the theoretical group. He has worked extensively on electronic a
 nd structural properties of surfaces developing the theory of low energy d
 iffraction and of electronic surface states.\nIn 1992 he turned his attent
 ion to photonic materials and developed some of the first computer codes c
 apable of handling these novel materials. This interest led to his present
  research into the remarkable electromagnetic properties of materials wher
 e the normal response to electromagnetic fields is reversed\, leading to n
 egative values for the refractive index. In collaboration with scientists 
 at Marconi he designed a series of metamaterials\, completely novel materi
 als with properties not found in nature.\nThese designs were subsequently 
 the basis for new concepts with radical consequences\, such as the first m
 aterial with a negative refractive index and a prototype cloaking device\,
  which have both caught the imagination of the world’s media.\nErwin Sch
 rödinger 1887-1961\nThe Erwin Schrödinger Lecture is an annual event\, h
 eld at Imperial College London\, named after the noted Austrian scientist.
  Schrödinger was a theoretical physicist and a significant contributor to
  the wave theory of matter\, a form of quantum physics. He mathematically 
 devised an equation of wave mechanics that bears his name. He was a co-rec
 ipient of the 1933 Nobel Prize for Physics. Today he is popularly known fo
 r the paradox of Schrödinger’s cat.
