根据多光束相互干涉理论，计算模拟了手性螺旋结构以及相关影响因素。模拟结果表明相干光束之间的夹角、偏振态、偏振方向以及光束相位差等参数，对于干涉形成的三维螺旋结构均有不同的显著影响。研究结果为螺旋结构的实验制备提供了理论指导，可促进手性超材料的研究及应用。

Based on multi-beam interference theory, the chiral spiral structure by interference lithography is simulated, and several factors that can influence the structures are discussed. The simulation results indicate that there are different special effects of incident angle, polarization status, polarization direction and phase difference on the three-dimensional spiral structures. The computer simulation of photonic crystal provides an effective guidance for the experimental fabrication, and promotes the development and applications of chiral spiral structures.
