Temporal fields for WSW with Gaussian envelope propagating through the designed metasurface with incident angles (a) θ 1 = 20° and (b) θ 2 = −20°, where white arrows show the theoretical propagating directions of the wave front, (c) and (d) the amplitude fields corresponding to panels (a) and (b), respectively.
