特异表面的异常折射特性研究

Study of the Reflection Properties of Metasurface

基于特异表面中各点的相位延迟精确可调的特性,设计了适用于太赫兹波段的特异表面,可用于实现光束传播方向的任意剪切和波前整形。对比研究了折射特性随入射光偏振态和相位分布不同而变化的规律,为实际应用提供了可靠的理论依据。

Based on the accurate phase delay manipulation properties of electrical field in any pixel, we proposed a Terahertz metasurface for adjusting and reshaping the wavefront. By comparing different incident polarizations and the phase profiles we got the different outgoing electrical field, those conclusion provide the parameters for application.
