DESCRIPTION:Electromagnetism encompasses much of modern technology. Its in
 fluence rests on our ability to deploy materials that can control the comp
 onent electric and magnetic fields. A new class of materials has created s
 ome extraordinary possibilities such as a negative refractive index\, and 
 lenses whose resolution is limited only by the precision with which we can
  manufacture them. Cloaks have been designed and built that hide objects w
 ithin them\, but remain completely invisible to external observers. The ne
 w materials\, named metamaterials\, have properties determined as much by 
 their internal physical structure as by their chemical composition and the
  radical new properties to which they give access promise to transform our
  ability to control much of the electromagnetic spectrum.
