摘要：

The light-trapping mechanism of the subwavelength nanorod arrays on a substrate is investigated theoretically. The simulated results show that the transmission and reflection of the arrays depend on the interference between the back-scattered light of the nanorods and the reflected light on the surface of the substrate. Because the radius and the height of the nanorods and the period of the arrays have important influences on the phase and the intensity of the back-scattered light, the reflection and the transmission vary with the parameters of the arrays. For the incident light with a single wavelength, it is possible to get zero-reflection by adjusting the parameters of the nanorod arrays.
