摘 要: | 基于传输线模型和弯曲金属线结构,设计一组太赫兹波段下波面整形透镜设计的基本单元,并据此进一步提出一种波面整形透镜的设计方案。此设计具有在亚波长尺度上对太赫兹波传输进行高效调制的重要特点,对太赫兹技术的发展推广和实际应用具有重要意义。 |
关 键 词: | 光学;太赫兹;波面整形透镜;负介电常数;相位调制 |

Abstract: | Based on the transmission-line model and a meander metal line structure, we proposed a design of a set of phase-modulating units working at terahertz, and a further design of a terahertz wavefront-shaping len was proposed. This proposal is demonstrated for terahertz wave transmission with high efficiency over a subwavelength scale, which yields crucial benefits for terahertz technology improvements and applications. |
Key words: | optics; terahertz; wavefront-shaping len; negative dielectric constant; phase modulation |
