Broadband transparent all-dielectric metasurfaces

We employ the generalized Huygens principle to design and fabricate highly transparent dielectric metasurfaces for complex wavefront manipulation with 99% polarization conversion and 99% diffraction efficiencies and broadband operation at telecom wavelengthsThe authors acknowledge financial support from the Australian Research Council.
