DESCRIPTION:Prof. Dr. Albert Polman. Institute AMOLF\, Amsterdam\nLight is
  a fascinating phenomenon. It determines how we observe the world around u
 s\, and vice versa\, gives us control over the world around us. Many aspec
 ts of our lives are controlled by light: we use the internet that is based
  on optical communication\, we watch movies from DVDs made by optical reco
 rding\, our homes are artificially lighted and we use light from the sun f
 or the generation of energy.\nThere are limits to the degree by which we c
 an control light. Light can only be effectively focused\, guided and manip
 ulated on a length scale that is larger than the wavelength. For many appl
 ications of light this limitation does not pose a problem. Recently\, howe
 ver\, it is being realized that some very intriguing novel physical phenom
 ena would become observable if we could control light on a scale well belo
 w the wavelength. Control over light at this small scale will also enable 
 applications that have never been foreseen before. \nIn this presentation 
 I will discuss how we can achieve control over light at the nanoscale\, i.
 e. some 10-100 times smaller than the wavelength of visible light. I will 
 discuss a novel class of materials\, called “metamaterials” in which t
 he propagation of light is not determined by the chemical materials compos
 ition as is traditionally the case\, but by sub-wavelength structure that 
 is artificially made in the materials. As a result it becomes possible to 
 engineer the flow of light in ways that are impossible to achieve with reg
 ular materials...\ncontinued on the web page dpwww.epfl.ch/seminars.html
