In recent years, due to the emergence of binary optics, greatly enriched the types of optical components, it has been widely used in more and more areas of the advantages of compact structure, light weight, flexible design, easy to copy. The binary optics theory is based on the theory of diffraction of light, theory of scalar diffraction grating has a more mature, but it only applied to the surface of the structural feature size is much larger than the incident wavelength of the optical elements. When the size of the surface structure and the incident wave looks scalar diffraction theory assumptions can no longer meet, then you need to use the electromagnetic vector diffraction theory analysis of grating diffraction properties. The rigorous coupled-wave analysis method is an electromagnetic vector diffraction theory, the process can be attributed to the departure from the Maxwell equations for solving differential equations combined with the appropriate boundary conditions. The grating diffraction characteristics, it can make a strictly accurate description, they have been widely used in the analysis and design of the grating. To improve the traditional rigorous coupled-wave analysis of grating diffraction problem, write a calculation program based on rigorous coupled wave analysis method, TM, TE polarization the case, for example, the diffraction efficiency and convergence the problems are analyzed and discussed.

In recent years, with the advent of binary optics, greatly enriched the kinds of optical element, it is designed with compact structure, light weight, flexible, easy to copy the advantages in the field of more and more widely used. Binary optics theory is based on the diffraction theory of light, at present, the grating of the scalar diffraction theory has been relatively mature, but it is only applicable to the surface structure characteristic dimension is greater than the incident wavelength of the optical element. When the surface structure size and the incident wavelength is cannot have satisfied the conditions of scalar diffraction theory, this is where the electromagnetic vector diffraction theory is used to analysis and study of grating diffraction properties. Rigorous coupled wave analysis method is a kind of electromagnetic vector diffraction theory, the process can be summed up in solving the maxwell
