| Summary: | The invention discloses a design and implementation method of a complex amplitude modulation metasurface device, and belongs to the field of metasurfaces. The method comprises the following steps: using isotropic unit structures with different geometric sizes as basic composition units of the metasurface device; the unit structure is a cylinder, and the transmittance and the phase of the wavefront can be adjusted at the same time by changing the radius and the height of the unit structure. The method has the characteristic of insensitivity to polarization, and can also realize complex amplitude modulation. Besides, the invention further provides a search algorithm which has the advantages of being high in robustness and easy to implement, a uniformly-distributed discrete value structure can be found from the two-dimensional parameter scanning data very easily, and the method is not only suitable for the method, but also suitable for other scenes with similar search requirements.
