摘要:
提出T形结构太赫兹频率编码器,其由初始相位值相同、相位灵敏度不同的4种同一形态、尺寸不一的T形编码超表面单元构成.利用预先设计的编码序列,实现对太赫兹波1 bit、2 bit编码和非周期太赫兹频率编码.无需重新设计编码器结构,仅通过改变工作频率,就可灵活控制反射太赫兹波的方向,理论计算与软件仿真结果吻合.提出的太赫兹频率编码器对反射太赫兹波主瓣能量具有很好的分散作用,能有效减少雷达散射截面.该器件在太赫兹波隐身中具有巨大应用价值.
Abstract:
We propose a terahertz frequency coding metasurface based on T-shaped structure. It is composed of four kinds of coding metasurface cells with the same initial phase value and different phase sensitivity. Based on the pre-designed coding sequence, 1 bit, 2 bit periodic and non-periodic terahertz frequency coding metasurfaces are realized. By changing the working frequency, terahertz wave radiation energy can be effectively controlled without redesigning the coding metasurface cell. The theoretical calculation results are in good agreement with the simulation results. The designed terahertz frequency coding metasurface has a good dispersion effect on the main lobe energy of the reflected terahertz wave and effectively reduces the radar scattering cross section. Our device has great application value in the terahertz wave stealth.
