CHAIR IN THEORETICAL SOLID STATE PHYSICS

Hill Memorial Library

  Dr. Pendry is a condensed matter theorist. He has worked at the  
Blackett Laboratory, Imperial College London, since 1981. He began his  
career in the Cavendish Laboratory, Cambridge, followed by six years  
at the Daresbury Laboratory where he headed the theoretical group. He  
has worked extensively on electronic and structural properties of  
surfaces developing the theory of low energy diffraction and of  
electronic surface states. In 1992 he turned his attention to photonic  
materials and in 2000 published a seminal paper (cited ~5000 times)   
on the "perfect lens," which has revolutionized nanoscale optics.

  In the last decade, a new area of research has emerged and the  
stimulus has been our ability to produce materials with entirely novel  
electromagnetic properties. Known as metamaterials for their ability  
to take us beyond conventional materials they give access to such  
remarkable effects as negative refraction. Spurred by the new  
opportunities theorists have produced exotic concepts which 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 specifications; we can guide radiation  
along an arbitrary trajectory so as to avoid objects, causing them to  
appear invisible; materials that are active magnetically in the  
optical range have been designed and manufactured. There has been a  
truly amazing amount of innovation but more is yet to come. The field  
of metamaterials is developing into a highly disruptive technology for  
a plethora of applications where control over light (or more generally  
electromagnetic radiation) is a prominent ingredient ­ amongst them  
telecommunications, solar energy harvesting, stealth, biological  
imaging and sensing, and medical diagnostics.
