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。

Based on the complementary media theory, we propose a way to transform a small object into a large one by coating it with a metamaterial shell with negative refractive index. Small waveguides made with this structure can replace large virtual tunnels to connect two separated waveguides. A small portal coating with complementary media is also designed in which a large entrance is concealed from electromagnetic wave detection. Two-dimensional numerical simulations are performed to illustrate the designed devices.
