摘要

本文提出了金属上硅图像化超表面不常见谐振区可控特性的理论表现，包括在主部分波之外激发一个额外的衍射阶以达到非镜面光反射。为了提供由光控制的强光-物质相互作用，研究了周期超表面双射线共振反射的Littrow方案。我们假设超表面是由位于金属衬底上的非线性硅纳米片阵列构成的。假定了移动天线中具有特定场分布对称性的米氏共振的激发。非镜面反射率和镜面反射率的比值可以通过调节入射波的强度来控制。

Non-specular reflection of light controlled by light

A theoretical manifestation of the controllable features of the uncommon resonant regime of the patterned silicon-on-metal metasurface is proposed involving the excitation of one additional diffraction order besides the main partial wave to reach a non-specular light reflection. As an attractive for applications, a Littrow scheme of double-ray resonant reflection by a periodic metasurface is investigated to provide a strong light-matter interaction controlled by light. We assume that the metasurface is constructed as an array of nonlinear silicon nanodisks located on a metal substrate. The excitation of a Mie-resonance that has a specific symmetry of field distribution used in mobile antennas is supposed. The ratio of values of non-specular and specular reflectance can be controlled by tuning the incident wave intensity.
