Description

technical field [0001] The invention relates to the field of antenna arrays, in particular to a manufacturing method and application of a metasurface nano-antenna array based on heavy ion track technology. Background technique [0002] With the development of nanotechnology, it is imperative to further enhance the optical imaging capability at the nanometer level, which will revolutionize the disciplines of materials science, chemistry and biology. The resolution of ordinary optical microscopes is limited by the diffraction limit, and the limit resolution that can be achieved λ 0 / 2 has long been unable to meet the needs of modern scientific research. Although later Kingslake invented the immersion microscope in 1983 and further reduced the resolution to λ 0 / 2n. However, due to the limitation of the range of the refractive index n of the medium, the resolution is still limited to a certain extent. Recently, several approaches have been proposed to break through the subw...
