Research on Beam Deflector and Super Lens Based on U-Shaped Hyperstructured Surface
One of the research hotspots in the field of optics is light manipulation using super surface. Herein, a U-shaped element structure is designed. The phase shift of transmitted light from 0 to 2π is realized by placing the structure in an oblique symmetrical manner and changing the geometric parameters of the structure. Using linearly polarized light, left-handed polarized light, and right-handed polarized light as incident lights, a beam deflector with polarization independent beam abnormal refraction is realized through structural optimization, and the refraction angle is 22.4°. The function of a super lens is also discussed, which provided a reference for the application of the super surface.
