Deskripsi
A single metasurface is used to generate multiple 3D knots with predesigned polarization profiles. At a given region, only a single 3D polarization knot can be obtained for a single color. Different 3D polarization knots can be obtained by changing the incident colors (left). The generated polarization structures are unveiled after passing through a linear polarizer (right).
