The electric field distributions near the metasurface in the x-z plane under a x-polarized and c y-polarized incidence. Normalized far-field intensity distributions for b x-polarized and d y-polarized normally incident light. The operating wavelength is 583 nm, and the transmitted angle is defined as positive (negative) value in the right (left) side of the normal
