(a) An non-paraxial light-shaping task, shaping a spherical wave with circular aperture into a uniform rectangle pattern. (b)(c) The calculated output phase gradient data, with x- and y-component respectively (Unit: 106rad/m and 105rad/m respectively). (d) The calculated output phase by direct numerical integration method with the gradient data (Unit: 104rad)
