(a) Distribution of the incident electric field \({E}_{y}\) in the x–y plane. The black box shows the electric field selected to calculate the OAM. (b) Distribution of the reflected electric field \({E}_{y}^{\mathrm{^{\prime}}}\). The arrow indicates the direction of the LM (the propagation direction of the reflected beam). The length is normalized to \({\lambda }_{0}.\) The field is normalized to \({m}_{e}{\omega }_{0}c/e(4\times 1{0}^{12}\mathrm{V}/\mathrm{m for }{\lambda }_{0}=0.8\mathrm{ \mu m}\)). (c) The k-space spectrum profile of the reflected beam. \({{\varvec{k}}}_{{\varvec{x}}}^{\mathrm{^{\prime}}}\mathrm{ and }{{\varvec{k}}}_{{\varvec{y}}}^{\mathrm{^{\prime}}}\) are the components of the wave vector in the x and y direction, respectively, normalized to \({k}_{0}\). The intensity is normalized to the peak intensity.
