The objective of this research is to understand the origins photo-spin current and obtain the current measurements along longitudinal and transverse direction of metasurface. The phase gradient and surface plasmon property of metasurface enhance the spin-orbit interaction, which allowing more observations and analyzations in photon spin manipulating applied in electronic-optical devices. For this research, we reproduce the interaction by employing circular polarization light normally impinging on metasurface and measure the current induced using Lock-in amplifier.
