a The transmission efficiency and b the corresponding phase variations of XLP light as a function of parameters a and b. c The co-polarized transmission efficiency and d corresponding phase variations of YLP light as a function of parameters a and b. The inset in a schematically shows the unit cell of periodic dielectric metasurface consisting of an array of silicon nanobricks on top of SiO2 substrate. The thickness of silicon nanobricks and SiO2 substrate is set as 900 nm and 200 nm, respectively
