摘要 | On the basis of the vector diffraction theory, the equation of two-dimensional grating in arbitrary angle of incidence is given, the complete analytical form of angular dispersion formula of two-dimensional grating is firstly deduced, and the concept of angular dispersion of diffractive polar angle (ADDPA) (the first kind angular dispersion) and angular dispersion of diffractive azimuthal angle (ADDAA) (the second kind angular dispersion) are established. In addition, according to theoretical analysis and numerical method on ADDPA and ADDAA of two-dimensional grating, the mechanism that diffraction spot array generates distortion is explained when the incidence wave has an angular deviation from the grating normal. Moreover, the conditions for causing mutation of ADDAA and leading to the dramatic change of diffraction spot array are also determined. This work, therefore, is of great importance in basic theory research. In practical application, taking x-ray diffraction, low-energy electron diffraction and reflection high-energy electron diffraction of crystal and quantum dot for example, we may take advantage of the above formula to test, analyze and explain the structure of a crystal lattice and the crystal growth process, then we can find new methods of characterizing crystal structure. |
