“…Due to the relatively strong response and highly localized resonance enhancement at the apex of the arrayed nanotips, surface waves with characteristic frequency can be effectively excited and transmitted along the surface of nanotips to the vertex [7][8][9][10][11]. Through continuous refraction and reflection, the surface electromagnetic wave field resonates and condenses at the tip, achieving enhanced resonance beyond the diffraction limit of the tip optical field, with a maximum intensity jump of over five orders of magnitude [12].…”

Metasurfaces, enabling effective optical modulation of incident lightwave, can be employed as a promising candidate to implement different functions, thus significantly improving the lightwave controllability, validity and system integration. In this paper, the phase and intensity modulation, firstly, of the incident lightwave based on a single nanotip was researched. Then, the metasurface consist of nanotips with different structural parameters was designed according to the grayscale image obtained via diffractive network encoding, so as to realize the extending image depth of field. We demonstrate that the metasurface based on the nanotips antenna can achieve a large image depth range of field exceeding 50μm. Moreover, the maximum focal length can reach ~200μm after passing through the arrayed nanotips.
