The mainstream transformation-optics-based optical illusions are inherently hindered by the extreme requirements of metamaterial compositions in practice and large computational cost. To address these issues researchers in China have proposed an intelligent optical illusion supported by form-free metasurfaces via a deep learning architecture which can render a similar illusion effect and greatly reduce the parameter space in physics. They have presented illustrative examples of conformal metasurfaces with a high-fidelity inverse design from either the near- or far-field in the simulation and experiment. They developed a full set of intelligent systems to benchmark the real-world optical illusion applicability. According to the researchers their work brings the available illusion strategies closer to a wide range of in situ practical-oriented applications and lays a foundation for the next generation of intelligent metamaterials…read more.
