Abstract
AbstractA metasurface is a planar structure that can flexibly control the polarization, phase, and amplitude of incident electromagnetic waves. An all‐dielectric hexagonal cell structure to reduce the interaction between cells and achieve efficient parametric regulation of electromagnetic waves is proposed. The single resonant transmission phase and the geometric phase are superimposed to realize the composite phase unit structure and construct a multifunctional flat metasurface device. The designed metasurface can flexibly tune the phase and polarization of incident electromagnetic waves and enable multifunctional integration phenomena, such as polarization separation, light intensity convergence, and vector light generation, on a single metasurface.
