Figure 1 | Principle of generating desired VOFs distributions by SW metasurface and characterization of the PB meta-atoms and plasmonic metal. a, The amplitude and phase of two orthogonal polarization states (LCP and RCP) for generating the desired VOFs. b, The design strategy of the on-chip composite MS constructed by the PB meta-atoms with individual rotation angle distributions for achieving the complex fields shown in (a). c-d, Schematic illustration and sample image of the designed meta-atom. e-g, Calculated and measured reflection phase, reflection amplitude and polarization conversion ratio (PCR) spectra of the periodic PB meta-atoms illuminated by the terahertz light linearly polarized along the two principal axes, i.e., u and v axes. h, Calculated dispersion relation of the eigen SW modes supported by the designed plasmonic metal (see the inset).
