Abstract

The finiteness of diffractive orders of the phase grating and the relations between the diffractive orders and the incident angle are discussed in this article. The distribution of each diffractive order is illustrated at different incident angles, and the diffractive direction of each diffraction wave is given. It is pointed out that while only the zero-order reflection wave and the zero-order transmit exist in the free-space layer, the diffraction waves of higher diffractive orders may exist in the substrate layer.
