Embodiment 1
[0019] First, an N (N>=1) layer multilayer structure (metal layer 3-liquid crystal material layer 4-metal layer 3-oxide layer 5) 2 is formed on a glass substrate 1 by a material growth process, as shown in the attached figure 2 (a) shown.
[0020] Second, deposit SiO on the multilayer structure 2 2 film as a mask 6, as attached figure 2 (b) shown.
[0021] Then, the designed periodic hole matrix sample is transferred to the mask through the mask process, as shown in the attached figure 2 (c) shown. Among them, the structure design can adopt algorithms such as finite time domain difference method and finite element method.
[0022] Then, through an etching process, a periodic hole matrix 7 is prepared on the 2 material, as shown in the attached figure 2 as shown in (d)
[0023] Finally, the mask 6 is removed to obtain the tunable metamaterial optical tweezers 8, as shown in the attached figure 2 (e) shown. Among them, the tunable metamaterial optical tweezers9 base...
Embodiment 2
[0025] First, an N (N>=1) layer multilayer structure (metal layer 3-liquid crystal material layer 4-metal layer 3-oxide layer 5) 2 is formed on a glass substrate 1 by a material growth process, as shown in the attached image 3 (a) shown.
[0026] Second, deposit SiO on the multilayer structure 2 2 film as a mask 6, as attached image 3 (b) shown.
[0027] Then, the designed periodic hole matrix sample is transferred to the mask through the mask process, as shown in the attached image 3 (c) shown. Among them, the structure design can adopt algorithms such as finite time domain difference method and finite element method.
[0028] Then, through an etching process, a periodic hole matrix 7 is prepared on the 2 material, as shown in the attached image 3 as shown in (d)
[0029] Finally, the mask 6 is removed, and liquid crystal material 4 is injected into the hole matrix 7 to seal the holes to obtain a tunable metamaterial optical tweezers 8, as shown in the attached im...
