DESCRIPTION:*Recently created Metamaterials are proving to be a disruptive
  technology where their ability to control the trajectory of light promise
 s improved telecommunications\, solar energy harvesting\, stealth\, biolog
 ical imaging and sensing\, and medical diagnostics.*\n\nIn the last decade
  a new area of research has emerged as a result of our ability to produce 
 materials with entirely novel electromagnetic properties. Known as metamat
 erials because they take us beyond the properties of conventional material
 s\, they display remarkable effects not found in nature\, such as negative
  refraction.\n\nSpurred on by these new opportunities\, theorists have pro
 duced exotic concepts that exploit the new materials: we can now specify h
 ow to make a lens whose resolution is limited not by the laws of nature bu
 t only by our ability to build to the stated specifications\; we can guide
  radiation along a trajectory\, avoiding objects and causing them to appea
 r invisible\; we can design and manufacture materials that are active magn
 etically in the optical range.\n\nThere has been a truly amazing amount of
  innovation but more is yet to come. The field of metamaterials is develop
 ing into a highly disruptive technology for a plethora of applications whe
 re control over light (or more generally electromagnetic radiation) is cru
 cial\, amongst them telecommunications\, solar energy harvesting\, stealth
 \, biological imaging and sensing\, and medical diagnostics.\n\nProfessor 
 Sir John Pendry\, a theoretical physicist at Imperial College London\, pio
 neered the field of metamaterials. In 2005 he was awarded the EU Descartes
  prize for “extending electromagnetism through novel artificial material
 s”. Then in 2006 he was awarded the Royal Medal by the Royal Society for
  his “seminal contributions to surface science\, disordered systems and 
 localisation\, and metamaterials and the concept of the perfect lens”. T
 his year he has been awarded a UNESCO-Niels Bohr gold medal\, for his “g
 round-breaking contributions to metamaterials”.\n\n"Add to calendar":htt
