Abstract
A metasurface structure for an antenna. The metasurface structure includes multiple subwavelength units operable to manipulate or control amplitude, phase, polarization, frequency, and momentum of electromagnetic waves for radiation. The metasurface structure may be operably coupled with a waveguide to provide a metasurface antenna. The metasurface structure or the metasurface antenna may be operably coupled with a controller arranged to control it.
