Title:
METASURFACE DESIGN METHOD AND APPARATUS, AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/066608
Kind Code:
A1
Abstract:
Provided in the present invention are a metasurface design method and apparatus, and an electronic device, the method comprising: determining n first nanostructures having different modulation phases for a main incident light; and cyclically executing an updating operation on a nanostructure set comprising the n target nanostructures until all the target nanostructures of the nanostructure set satisfy the requirement of wide-angle imaging, the initial target nanostructure being the corresponding first nanostructure; and designing a metasurface on the basis of the nanostructure set. The updating operation comprises replacing a target nanostructure not satisfying the requirement of wide-angle imaging with a second nanostructure, so as to generate a new nanostructure set. The technical solution provided in the embodiments of the present invention can replace a nanostructure which does not satisfy the requirement of wide-angle imaging with a nanostructure of other shapes, so as to achieve updating. Thus, a nanostructure having a relatively small resonance response can be found, thereby achieving design of metasurfaces. The designed metasurface has a relatively good overall performance and can be suitable for wide-angle imaging scenarios.
