(a) Schematic of the slant-perturbation metasurface with GST-225 phase-change material. (b) Disturbance diagram of in-plane deformation Angle α and out-of-plane inclination Angle β. The geometric parameters are: a = 1300 nm, b = 1000 nm, h = 500 nm. (c) The illustration of the phase transition of GST-225 from the amorphous state to the crystalline state.
