DESCRIPTION:Electrically thin composite layers (metasurfaces) can be used t
 o realize extremely thin absorbers\, lenses\, focusing reflectors\, and mo
 re. Conventionally\, the design of metasurfaces as well as reflectarray an
 d transmitarray antennas has been based on assuring the desired reflection
  or transmission properties at every point of the metasurface area\, using
  so called generalized laws or refraction and reflection. We will show tha
 t this approach in fact does not lead to exactly the required performance.
  Furthermore\, we will show how it is possible to create metasurfaces whic
 h function exactly as is required by the design specification. The results
  will be illustrated on the examples of perfect anomalous reflection and r
 efraction of plane waves and on some “multi-channel” metasurface devic
 es: perfect power splitters and three-channel mirrors.\n\nSpeaker(s): Serg
