摘要：
To calculate the optical parameters, the finite difference method in the time domain (FDTD) was used, which can be applied to solve Maxwell's equations. A large number of combinations of a planar structure with metal nanoparticles and a structure with nanowires and metal nanoparticles (NPs) were calculated. The height of nanowires h varied from 50 to 3000 nm, the period of the structure P was 100-600 nm, and the diameter of metal nanoparticles d was 50-400 nm. The reduction of light reflection was determined by the anti -reflection effect of the Si-NWs array itself and the direct scattering effect of metal nanoparticles. It was shown that all structures gave significantly lower reflection coefficients compared to that of a solid silicon plate.
