As an ultrathin flat platform for versatile electromagnetic wave manipulation in both near-field and far-field, metasurfaces consist of arrays of subwavelength inclusions made of plasmonic, dielectric, or even 2D materials have attracted enormous interest in recent years. By wisely tailoring the structure and the material composite of the subwavelength inclusions, a number of degrees of freedom could be developed, leading to multi-dimensional manipulation of an electromagnetic wave in terms of phase, amplitude, polarization, frequency, and orbital angular momentum. It promises to address some compelling demands from both fundamental and application aspects of optics and electromagnetics and may open new frontiers in adaptive cameras, microscopes, portable and wearable devices, and artificial neural networks.
Ultrathin metasurface has recently been developed to realize spectral resonance tuning, polarization control, structured light manipulation, 3D holographic displays, surface wave coupling, nonlinear information processing, and image multiplexing and encryption. However, many existing problems hinder its deployment from a lab demonstration to practical applications, including device efficiency, bandwidth, functionality, dynamic tunability, fabrication cost, and photonic integration with other platforms. To address these problems, we are keen to see recent advances in the multi-dimensional metasurface field, including metasurface spectral tailoring, metasurface polarization control devices, vectorial holograms, 2D materials metasurfaces, nonlinear metasurfaces, new algorithms for metasurface design based on deep learning and inverse design, metasurface neural networks, advanced nanofabrication platforms for digitizing metasurfaces, integration of metasurface with various applications such as optical trapping, pattern recognition, biosensing, image processing, polarization imaging, single-photon, and quantum sources. This research topic offers a great opportunity to showcase recent efforts toward developing multi-dimensional metasurfaces for different electromagnetic applications.
