| Abstract: | Based on the Maxwell equation and the boundary continuity of electromagnetic field ,the vector theory analysis method-the rigorous coupled-wave analysis technique for describing the diffraction of electromagnetic waves by any shape profile gratings for both TE and TM polarization is presented. For any shape profile gratings ,the distribution of diffraction efficiency with TE and TM polarization are given.The effect of grating structure parameters, incident angle and polarization on field is investigated. |
