Abstract: An optical device includes a nanostructured transparent dielectric film, which is a Huygens metasurface. The Huygens metasurface imparts a phase change to light propagating through or reflecting from the surface. The phase change can be achieved by means of a resonant interaction between light and the Huygens resonators, resulting in a controllable phase change of 0 to 2? with approximately 100% light transmission characterized by a below 0.1 dielectric loss tangent of delta and with the height of the resonators less than the wavelength of light. In one embodiment, the metasurface includes titanium dioxide, but many materials or stacks of different materials may be used. The optical device is functional throughout the visible spectrum between 380 and 700 nm. The nanostructured transparent dielectric film includes a plurality of Huygens resonators.
