Supporting data for "Metasurface for 'vision' improvement".

This dataset is for the thesis titled "Metasurface for 'vision' improvement". It contains the SEM (scanning electron microscopy) images of metasurfaces used throughout the thesis. And it contains the simulation video for Laguerre-Gaussian modes decomposition results. In general, this thesis mainly presents the design and application of metasurface devices to improve "vision" in three aspects, namely, signal "vision", holographic "vision", and biomedical "vision". The design techniques spread from forward calculation, neural network, to adjoint optimization. These methods are dedicated to finalize the exact metasurface patterning for a desired far-field radiation, which, if properly defined, can be beam profiles in signal "vision", 2D intensity distribution in holographic "vision", or depth of focus distribution in biomedical "vision".
