Metasurface antenna and metasurface structure for antenna

A metasurface structure for an antenna. The metasurface structure comprises a plurality of sub-wavelength units which can manipulate or control the amplitude, phase, polarization, frequency and momentum of radiated electromagnetic waves. The metasurface structure may be operably coupled with the waveguide to provide a metasurface antenna. The metasurface structure or the metasurface antenna may be connected with a controller for controlling the metasurface structure or the metasurface antenna. 一种用于天线的超表面结构。超表面结构包括多个亚波长单元，可操纵或控制辐射电磁波的振幅、相位、极化、频率和动量。超表面结构可与波导可操作地耦合，以提供超表面天线。超表面结构或超表面天线可与用于控制超表面结构或超表面天线的控制器连接。
