“…The tunablity in metasurfaces can be enabled by incorporating PIN diodes in the structure design [144][145][146]. For example, switchable perfect absorbers and reflectors using a PIN diode integrated active frequency selective surface (AFSS) have attracted enormous interest [147][148][149]. Varactor, another electrically sensitive element, is an excellent candidate for achieving reconfigurable metasurfaces.…”

Polarization is an important characteristic of electromagnetic waves that has been exploited in many areas of wave manipulations. While effective control of polarization is highly demanded in various applications, traditional polarization converters have drawbacks such as large volume, narrow operating frequency band, low efficiency, and high losses, hindering themselves from practical applications. Metamaterials and metasurfaces are recently developed artificially structured electromagnetic materials constructed by three- or two-dimensional arrays of meta-atoms with tailored electromagnetic responses, exhibit great potential in controlling the propagation of electromagnetic waves and are highly suitable for flexible control of polarization. Here, we review the recent developments in the field of electromagnetic metamaterials and metasurface for polarization manipulation, focusing on their operation principles and practical applications. We discussed the research progress of chiral metamaterials and anisotropic metasurfaces, and also summarized the achievements of metasurfaces for comprehensive manipulation polarization and phase in recent years. We further summarize the recent achievements on the diversified polarization manipulation functions of metasurfaces. Finally, we discuss reconfigurable metasurfaces that can dynamically control the polarizaiton and wavefronts of electromagnetic waves, including not only electrically reconfigurable metasurfaces with constitutional meta-atoms locally tuned by external stimuli, but also time-modulated metasurfaces exploiting the temporal dimension by applying dynamic switching of the coding sequences. Finally, we look forward to the possible future directions and existing challenges in this rapidly developing field.

“…Recently, switchable perfect absorbers and reflectors using a PIN diode integrated active FSS (AFSS) have attracted enormous interest [70,71,137] . For example, Zhao et al proposed a metasurface that can be electronically switched between the reflection and absorption modes by a PIN diode [137] . Such an AFSS absorbs almost all incident power at 3.5 GHz for the 'ON' state, while showing total reflection for the 'OFF' state.…”

Metasurfaces are ultrathin metamaterials constructed by planar meta-atoms with tailored electromagnetic responses. They have attracted tremendous attention owing to their ability to freely control the propagation of electromagnetic waves. With active elements incorporated into metasurface designs, one can realize tunable and reconfigurable metadevices with functionalities controlled by external stimuli, opening up a new platform to dynamically manipulate electromagnetic waves. In this article, we review the recent progress on tunable and reconfigurable metasurfaces, focusing on their operation principles and practical applications. We describe the approaches to the engineering of reconfigurable metasurfaces categorized into different classes based on the available active materials or elements, which can offer uniform manipulations of electromagnetic waves. We further summarize the recent achievements on programmable metasurfaces with constitutional meta-atoms locally tuned by external stimuli, which can dynamically control the wavefronts of electromagnetic waves. Finally, we discuss time-modulated metasurfaces, which are meaningful to exploit the temporal dimension by applying a dynamic switching of the coding sequence. The review is concluded by our outlook on possible future directions and existing challenges in this fast developing field.

“…Recently, switchable perfect absorber/reflectors with a PIN diode integrated active frequency selective surface have attracted enormous interest (Yoo and Lim, 2014;Ghosh and Srivastava, 2016). In 2019, Zhao et al proposed an electrically reconfigurable metasurface that can be switched between reflection and absorption modes by loading PIN diodes (Zhao et al, 2019). Perfect absorption occurs when the impedance of the dielectric substrate matches well with the free-space impedance while total reflection occurs when they mismatch.…”

Metasurfaces, a kind of two-dimensional artificially engineered surfaces consist of subwavelength unit cells, have recently attracted tremendous attention, owing to their exotic abilities for tailoring electromagnetic responses. With active lump elements incorporated into the design of metasurfaces, dynamic reconfigurabilities enabled by external stimuli could be realized, offering opportunities for the dynamic manipulation of electromagnetic waves. In this mini review, we present a brief review on the recent progress of electrically reconfigurable metasurfaces at microwave frequencies. A brief discussion will also be given with our outlook on future development direction and possible challenges in this interesting field.
