摘要
High-refractive-index nanoparticle two-dimensional arrays have attracted a lot of interest recently, as they support both electric and magnetic resonances and can be implemented as functional metasurfaces. Here we show that under particular conditions, the all-dielectric nanoparticle metasurfaces can resonantly suppress transmission. As an important example, resonant electric and magnetic dipole (MD) responses of silicon nanoparticle arrays are considered in the air, as well as in the dielectric matrix in visible and infrared spectral ranges. We show that the wave resonantly scattered forward by one or both electric and MD moments of nanoparticles can destructively interfere with the incident wave, providing significant suppression of the transmission through the array. The reported effect can find important applications in different fields related to optics and photonics such as the development of filters, sensors, and solar cells.
