Metasurfaces, two-dimensional equivalents of metamaterials, are engineered surfaces consisting of deep subwavelength features that have full control of the electromagnetic waves. Metasurfaces are not only being applied to the current devices throughout the electromagnetic spectrum from microwave to optics but also inspiring many new thrilling applications such as programmable on-demand optics and photonics in future. In order to overcome the limits imposed by passive metasurfaces, extensive researches have been put on utilizing different materials and mechanisms to design active metasurfaces. In this paper, we review the recent progress in tunable and reconfigurable metasurfaces and metadevices through the different active materials deployed together with the different control mechanisms including electrical, thermal, optical, mechanical, and magnetic, and provide the perspective for their future development for applications.

• Electromagnetic metasurfaces: physics and applications (2019, neutral): “While the past decade has witnessed rapid development in active and tunable metasurfaces, several major challenges need to be overcome before such devices can be used in practice [384].”
• Spatiotemporal light control with active metasurfaces (2019, background): “The first wave of active metasurfaces very much resembles static metasurfaces in which the passive materials and building blocks (meta-atoms) are replaced by active counterparts whose optical response can be altered with an external stimulus (7).”
