Abstract

Metasurfaces that derive their properties from single- or multi-layer planar artificial structures represent new advances in nano-optics. Careful structural engineering allows metasurfaces to achieve strong light–matter interactions on subwavelength scales, while avoiding complex and difficult three-dimensional nanofabrication processes. Nevertheless, metasurfaces usually exhibit fixed responses, primarily determined by the geometric arrangement of meta-atoms, which can limit their usefulness in practical applications if adequate meta-atoms cannot be designed. Meanwhile, recent years have witnessed tremendous growth in the research of reconfigurable metasurfaces with the increasing demand for new design strategies and mechanisms for realizing dynamic control of optical systems. The sections that follow discuss emerging metasurfaces based on state-of-the-art inverse-design techniques and temporal media for achieving sophisticated tailored optical functionalities.
