Fundamentals and Applications of Metasurfaces

Metasurfaces have become a rapidly growing field of research in recent years due to their exceptional abilities in light manipulation and versatility in ultrathin optical applications. They also significantly benefit from their simplified fabrication process compared to metamaterials and are promising for integration with on‐chip nanophotonic devices owing to their planar profiles. The recent progress in metasurfaces is reviewed and they are classified into six categories according to their underlying physics for realizing full 2π phase manipulation. Starting from multi‐resonance and gap‐plasmon metasurfaces that rely on the geometric effect of plasmonic nanoantennas, Pancharatnam–Berry‐phase metasurfaces, on the other hand, use identical nanoantennas with varying rotation angles. The recent development of Huygens' metasurfaces and all‐dielectric metasurfaces especially benefit from highly efficient transmission applications. An overview of state‐of‐the‐art fabrication technologies is introduced, ranging from the commonly used processes such as electron beam and focused‐ion‐beam lithography to some emerging techniques, such as self‐assembly and nanoimprint lithography. A variety of functional materials incorporated to reconfigurable or tunable metasurfaces is also presented. Finally, a few of the current intriguing metasurface‐based applications are discussed, and opinions on future prospects are provided.

“…Within the homogenization procedure, which depends on the constituent materials and geometry, one can describe a nonmagnetic achiral 2D uniaxial plasmonic layer by effective conductivities along (\sigma \| ) and across (\sigma \bot ) the main axis. For a light with the plane of incidence is at an angle \varphi to the main axis, the rotated conductivity tensor should be used [9,30]:…”

A comprehensive analysis of hybrid TM-TE polarized surface electromagnetic waves supported by different few-layer anisotropic metasurfaces is presented. A generalized 4\times 4 T-matrix formalism for arbitrary anisotropic 2D layers is developed, from which the general relations for the surface waves dispersions and scattering coefficients are deduced. Using this formalism and the effective conductivity approach, the dispersions and iso-frequency contours (IFCs) topology of the surface waves in various hybrid uniaxial metasurfaces are studied. The existence of hyperbolic plasmon-exciton polaritons in plasmon-exciton hybrids and hyperbolic acoustic waves with strong confinement in both out-of-plane and in-plane directions in uniaxial plasmonic bilayers are predicted. In plasmonic uniaxial metasurfaces on metal films, the elliptic and hyperbolic backward surface waves with negative group velocity are predicted and additional topological transitions in both elliptic and hyperbolic IFCs of the hybrid surface waves are revealed. Ultrathin twisted uniaxial plasmonic bilayers are proposed as systems with the IFCs topological transitions highly sensitive to the layers twist. The developed formalism may become a useful tool in the calculation of multifunctional few-layer metasurfaces or van der Waals heterostructures based on 2D materials with in-plane anisotropy, where the TM-TE polarization mixing must be considered. The predicted effects may open new horizons in the development and applications of planar optical technologies.plasmon-exciton polaritons (plexcitons [60]) may become a modern platform for ultrafast active control of light [38,39,61] and room temperature polariton lasing [62].Over the past few years, the 2D materials research has grown into the broader field, which includes the study of van der Waals heterostructures [63] and transdimensional materials [64]. Similar to van der Waals materials, which for some applications are more effective in a fewlayer configuration than in a monolayer one [58,59,65], the applicability of metasurfaces can be dramatically improved by going to the few layers. The multiplication of metasurface layers, while retaining a relatively low level of losses and fabrication simplicity, can provide higher efficiency and more degrees of freedom for manipulating the phase, amplitude, polarization, propagation, and dispersion of light [66,67]. Moreover, the layers interaction results in additional effects, including near-field coupling, WG modes, and multiple wave interference [68]. The WG effects enable us to control polarization and phase of the transmitted light simultaneously [69], while multiple interference effects can be used to cancel the undesired light and enhance the efficiency of antireflection coatings [70], polarization converters [71,72], and metalenses [73]. Near-field coupling generates a magnetic resonance inside the structure, which being effectively coupled to an in-layer electric resonance allows us to realize perfect absorbers and reflectors [74--76]. Such a magnetic ...

“…Specifically, we consider graphene strips (GS) in this work. The homogenization of such a metasurface in the subwavelength approximation (L<<λ) can be done using the effective medium theory based on the electrostatic approach [45]. It is shown that the GS can propagate plasmons along large distances compared to the plasmons' wavelength [46].…”

Metasurfaces, the two-dimensional (2D) counterpart of metamaterials, have recently attracted a great attention due to their amazing properties such as negative refraction, hyperbolic dispersion, manipulation of the evanescent spectrum. In this work, we propose a theory model for the near field radiative heat transfer (NFRHT) between two nanoparticles in the presence of an anisotropic metasurface. Specifically, we set the metasurface as an array of graphene strips (GS) since it is an ideal platform to implement any metasurface topology, ranging from isotropic to hyperbolic propagation. We show that the NFRHT between two nanoparticles can not only be significantly amplified when they are placed in proximity of the GS, but also be regulated over several orders of magnitude. In this configuration, the anisotropic surface plasmon polaritons (SPPs) supported by the GS are excited and provide a new channel for the near-field energy transport. We analyze how the conductance between two nanoparticles depends on the orientation, the structure parameters and the chemical potential of the GS, on the particle-surface or the particle-surface distances by clearly identifying the characteristics of the anisotropic SPPs such as dispersion relations, propagation length and decay length. Our findings provide a powerful way to regulate the energy transport in the particle systems, meanwhile in turn, open up a way to explore the anisotropic optical properties of the metasurface based on the measured heat transfer properties.
