 rial College)

DESCRIPTION:Sir John Pendry from Imperial College gives a talk on controll
 ing light in the world of nanoscience - see the abstract below for more de
 tails.\n\nAdmission is free to CUPS members\, or £2 otherwise. As always\
 , wine and cheese will be served after the talk.\n\n(Abstract:) Convention
 al optics controls light on the scale of roughly a micron - ­approximatel
 y the wavelength of visible light. To control light in the world of nanosc
 ience requires a new understanding in which we look inside the wavelength 
 at the component electric and magnetic fields. Exploiting the new concept 
 of ‘transformation optics’ we have designed devices that compress ligh
 t into less than a square nanometre opening the way to single molecule sen
 sing and switching light with light ­ the optical transistor. Finally I s
 hall discuss negative refraction and how it leads to the construction of a
  lens whose resolution is unlimited by the wavelength of light.
