【摘要】:超颖表面是近些年刚发展起来的一个有着重要应用潜力的新兴前沿领域。文中在对超颖表面研究现状的分析基础上,提出并研究一种基于棒形纳米天线阵列的超颖表面,在手性圆偏振光场作用下产生无色散的表面相位突变,从而对出射光波前相位进行调控,并在此基础上研究若干新颖功能应用,包括依赖于手性的广义折/反射定律,双极性可控平板透镜,宽带涡旋光束生成,手性选择性表面等离激元定向激发,三维纳米全息等。
[Abstract]:Superglume surface is a new frontier field with important application potential which has been developed in recent years. In this paper, based on the analysis of the present research situation of superglume surface, a novel superglume surface based on a rod array is proposed and studied, which produces a non-dispersive phase change on the surface under the action of chiral circular polarized light field. On the basis of this, some novel applications are studied, including the chiral generalized refraction / reflection law, the bipolar controllable plate lens, and the generation of wideband vortex beams. Chiral selective surface isophosphoric directional excitation, 3 D nano holography and so on.
