Abstract: To take advantage of metasurfaces in visualization systems, one of the main challenges is to resolve the question of the manufacturing device surface. Nanosphere self-assembly can be used to define the elementary pattern of periodic metasurfaces on large areas. Combined with soft UV-NIL (nanoimprint lithography), it allows the fabrication and reproduction of large surface structures. As self-assembly can be carried out on different surfaces, this adds flexibility to the manufacturing process: here we compare silver metasurfaces made by soft-UV NIL, with two different ways for PDMS stamps fabrication, both of which use self-assembly of the same polystyrene nanospheres. We describe both processes and their respective impact on the characteristics of the obtained metasurfaces.
