(a) Sketch of the LC alignment model. Polar angle θ and azimuthal angle φ define the spatial alignment of LC molecules with respect to the x-axis corresponding to the photo-alignment direction of the LC cell. The alignment direction is defined by the long axis of LC molecules. (b) Calculated transmittance spectra of the TiO₂ nanodisk metasurface after LC infiltration for the incident light polarized in-plane along (i) φ = 0°, (ii) φ = 45° and (iii) φ = 90° directions, with LC alignment set in-plane parallel to the x-axis (θ = 90°, φ = 0°). The dashed line shows the experimental results for incident polarization parallel to φ = 0°.
