“…Clearly, the most conspicuous property of the plasmonic dispersion is the fact that its propagation constant could be much larger than that in the dielectric host, as a result of the collective resonance of the free electrons and photons . This property is responsible for the extraordinary Young's interference, and has led to many practical applications such as plasmonic nanolithography, ultrathin plasmonic flat lens, and color filtering …”

IntroductionMetasurfaces and surface waves are two booming research branches in modern optics and wave physics. As 2D counterparts of 3D metamaterials, metasurfaces have inherited many unusual properties of artificially structured metamaterials, e.g., negative refraction, super-resolution imaging, and invisibility. [1][2][3][4][5][6] Nevertheless, owing to the reduced dimension, metasurfaces are much easier to fabricate, thus providing possibilities to transform theoretical innovations to practical applications. [7,8] In principle, the mechanisms of light-matter interaction in metasurfaces are related to the exotic physical properties of surface waves on metasurfaces. There are many kinds of surface waves propagating along interfaces of two kinds of media, such as surface plasmons, Dyakonov, Bloch, and Tamm surface waves. [9,10] Surface plasmons require that one of the media has negative permittivity; Dyakonov surface waves require linear anisotropy of at least one of the media. Bloch and Tamm surface waves require periodic permittivity of one of the media truncated by the interface or along the interface. In this paper, we would like to highlight the Dispersion is one common yet critical property of all kinds of waves. It is related to the spatial and spectral evolution of waves in structured materials. This review gives a summary of the methodologies used for the on-demand dispersion engineering of waves in metasurfaces, which possess many unusual properties such as extremely short wavelength, diffraction-less directional propagation, and tunable phase shift, resulting in many exciting applications with performances beyond the limitations set by traditional geometric and physical optics. Since most metasurfaces could be continuously transformed from simple thin films, the methodologies proposed here are universal and may be applied to analyze and design various functional metasurfaces. Dispersion EngineeringWithout loss of generality, the geometry of almost all metasurfaces could be continuously transformed from simple thin films. The transformation process is illustrated in Figure 1. First, by stacking and bending multilayers, one obtain the superlens, planar hyperlens, and curved hyperlenses. [26][27][28] The hyperbolic dispersion in anisotropic metal-dielectric structures may lead to the formation of Dyakonov plasmons, which are similar to Dyakonov waves on anisotropic dielectric materials. [29][30][31][32][33][34] Second, a 90° rotation of the multilayer would result a 1D grating, which can be either periodic or gradient. Third,

“…As its geometric dimensions are comparable to the wavelength of visible light, a periodic array of nanostructures exhibits optical resonances at visible wavelength, thereby producing color that corresponds to the scattering spectrum. The structural color generation by the metasurfaces has been successfully demonstrated in plasmonics [1][2][3][4][5][6] and dielectric systems [7][8][9][10][11] using a variety of designs (See review papers [12][13][14][15][16] for details). However, as the geometry of nanostructures specifies scattering properties, an array of nanostructures usually produces only one fixed color.…”

Abstract:Generating colors by employing metallic nanostructures has attracted intensive scientific attention recently, because one can easily realize higher spatial resolution and highly robust colors compared to conventional pigment. However, since the scattering spectra and thereby the resultant colors are determined by the nanostructure geometries, only one fixed color can be produced by one design and a whole new sample is required to generate a different color. In this paper, we demonstrate active metasurface, which shows a range of colors dependent on incident polarization by selectively exciting three different plasmonic nanorods. The metasurface, which does not include any tunable materials or external stimuli, will be beneficial in real-life applications especially in the display applications.

“…The development of photonic materials is an attractive topic in materials science due to the numerous applications and scientific importance of these materials [1][2][3]. Structural color materials are types of photonic materials and are based on the optical interaction between light and submicron-sized structures [4][5][6]. There are several types of structures that produce structural colors, for example, reflection, diffraction, interference, and diffusion.…”

By selecting the core materials and grafted-hair polymers, hairy particles with polymer brushes can create various types of functional materials. In recent years, polydopamine (PDA) particles that are obtained by polymerizing dopamine, which is an amino acid derivative, have attracted attention for various applications. Herein, we present a novel approach for creating photonic and magnetic materials from hairy PDA particles. By grafting a hydrophilic hair polymer, we have succeeded in producing photonic materials capable of structural color changes. Furthermore, we have demonstrated the preparation of magnetic materials by immobilizing holmium, which is one of the lanthanide elements, by electrostatic interactions onto a cationic hair polymer. These results demonstrate the possibility of hairy PDA particles for a wide range of applications, such as for photonic and magnetic materials.
