Metaphotonics allows us to encode optical responses such as amplitude and phase at the deep subwavelength scale, thereby enabling unprecedented opportunities in the control of light. A large variety of components has been reported, including lenses, holograms, polarizers, carpet cloaking, etc. This special symposium will focus on two emerging applications of metaphotonics: the computational imaging and time-dependent modulation. Combining computational imaging and metasurfaces is a promising avenue toward highly efficient imaging systems and may enable novel imaging processing in computer vision, physical sciences, and machine learning. The first part will provide a wide range of talks on methods and applications of imaging, through a synergistic combination between computational imaging and metaphotonic devices in terms of mathematical theory, physical models, and algorithms. In addition, there have been rapidly growing interest in reconfigurable metasurfaces for applications ranging from light detection and ranging (LiDAR) to holographic displays. Many challenges still remain unresolved such as the limited modulation efficiency and difficulty in the implementation of individually-addressable pixels without crosstalk. The second part of this special symposium aims at providing a forum for cross-cutting discussions on novel fundamental approaches to overcome issues of reconfigurable metasurfaces in pursuit of practical applications.
