The invention discloses a meta-structure surface member generating a nanometer scale vertical light spot chain and a generation method thereof. Nanometer antennas of different orientations and sizes perform scattering on incident light. Phases of diffusion light are abruptly changed differently. Nanometer antennas of different orientations are constituted into an array according to a certain ruleso as to form a metal-structure surface member, and thus equal interval multi-point focusing along an axial direction on incident circularly polarized light is realized and a light spot chain is produced. During a designing process, the surface of a material is divided into square unit arrays, wherein the square unit is of a sub-wavelength size. When the center of the square unit is arranged on adetermined radius and azimuth, a corresponding phase modulation value is applied.

The meta-structure surface member generating the nanometer scale vertical light spot chain and the generation method thereof can form minisize optical tweezer probes for vertically arranging or piling controlled nanometer particles.
