The nonlinearity of the metasurface is essential in this transformation of light. A linear metasurface would filter the incoming light and allow only the specific polarization of the light to pass ...

Compared to traditional optical technologies, metasurface technology offers more advanced, lighter, and precise light control using nanometer-sized artificial structures. Researchers at KAIST have ...

c, The flexible LCE metasurface and the microscopic image of the C-shape split rings. The thick black line in the middle indicates the illumination position of the line-focused infrared light.
