Figure 4

(a) The experiment setup, in which an X-band metamaterial lens antenna is used as an excitation to generate the linear-polarized incident plane waves. (b) The photograph of fabricated metasurface. (c) The measured far-field patterns, in which the solid lines are vertical (y) polarizations and dashed lines are horizontal (x) polarizations.
