%X A polarization control device was developed using a plasmonic metasurface with the aim of achieving the desired polarization state. In this study, the Ag metal grating structure was fabricated as a plasmonic metasurface by electron beam lithography and a lift-off process. The phase difference of the fabricated sample was 21.0&deg;. This value is almost consistent with the simulation (24.0&deg;). Then, the transmission and phase difference is dependent on the structural parameter. Because of the propagation of surface plasmon polariton at the interface between Ag and SiO<sub>2</sub> or Ag and air, it is believed that the transmittance and the phase difference for TM polarized light can be controlled by the structural parameters. By plotting on the Poincar¨¦ sphere after calculating the S-parameter by simulation, it is clear that the arbitrary polarization status can be controlled by the structural parameter.
