Fig. 3. — (A) Amplitude and phase responses of the designed multilayer films for different incident angles. (B) Actual reflection coefficients of the whole metasystem, including the amplitude r(x) and reflection phase φ_r(x). (C) Actual energy flow distribution of S_pz. An interference pattern is produced by the incident wave and perfect anomalous-reflection wave. (D) The arrows represent the direction of S_p in the xz plane. Lateral energy transfers exist in both the spacer and metasurfaces. (E) SEM side view image and cross-sectional image of the sample. (F) Broadband spectra measured in the experiment and calculated in the design.
