Two-dimensional terahertz beam scanning with a programmable liquid crystal metasurface
Chaoming Xia, Dongyang Liu, Lan Wang, Xin Gao et autres
We demonstrate a programmable terahertz (THz) metasurface enabling two-dimensional (2D) beam steering. Existing THz metasurfaces based on liquid crystal (LC) often provide insufficient continuous phase coverage, which limits the phase gradients required for synthesizing flexible and precise phase patterns. Here, we propose …
