 t\n\nWe will describe the concept of the Huygens&#39; metasurface which compri
 ses co-located electric and magnetic dipoles forming an electrically dense
  array of Huygens&#39; sources or scatterers. These engineered surfaces can be
  designed to control electromagnetic waves at will. Both passive and activ
 e Huygens&#39; metasurfaces can be envisioned. Unlike traditional antenna tran
 smitarrays\, Huygens&#39; metasurfaces can be made sub-wavelength thin and dev
 oid of spurious Floquet modes\, while preserving excellent matching charac
 teristics. Huygens&#39; metasurfaces can be used to manipulate the phase\, mag
 nitude and polarization of incident electromagnetic waves\, including thos
 e from nearby elementary antennas\, for a variety of applications. For exa
 mple\, Huygens&#39; omega bi-anisotropic metasurfaces enable wave refraction a
 t extreme angles without any reflections. They also allowed the demonstrat
 ion of generalized flat reflectors having arbitrary angles of incidence an
 d reflection and with 100% theoretical efficiency. Examples of Huygens’ 
 metasurface applications include ‘perfect’ wavefront refraction\, focu
 sing and lensing\, polarization control including chirality\, active cloak
 ing\, high-aperture efficiency/low-profile antennas\, and antenna aperture
  beamforming with simultaneous magnitude and phase control.\n\nCo-sponsore
