摘要：
This study explores the use of passive and flexible optics elements to achieve THz beam profile engineering for imaging applications via mechanical bending. Specifically, a stainless steel-based C-shaped metasurface was designed and fabricated using laser ablation technology. The metasurface performance and polarisation manipulation were experimentally evaluated for different focal distances and geometrical metaatom parameters. Experimental data are well supported by simulations using the Finite Difference Time Domain method. The results obtained pave the way to achieve accurate beam profile engineering and resolved polarisation in THz imaging.
