“…To minimize the influence of adjacent coupling, a careful choice of the geometric parameters is often needed. [127][128][129] Furthermore, the elimination of the effect of near-field evanescent coupling on the focusing efficiency is still a challenge. [130] Compared with the dielectric flat lens, the metallic one may have relatively low efficiency, but the polarization selectivity is much higher.…”

with the development of nanofabrication, characterization, and numerical modeling techniques, research has focused on optical applications in the subwavelength region, where the characteristic dimension of light-matter interactions is below the operating wavelength. [7,8] It was found that catenary functions have played more important roles in this new realm. [9] First, the coupling of evanescent waves, such as surface plasmon polaritons (SPPs) leads to catenary-shaped intensity distributions, [10,11] which have found practical applications in super-resolution imaging and lithography. [12-15] Second, catenaryshaped subwavelength structures have been proved to be ideal candidates for generating geometric phases, which are widely utilized to construct various functional metasurfaces. [2,16-18] Furthermore, besides the field intensity distribution, the dispersion curves of many capacitive metasurfaces were found to be characterized by the catenary function, [3] which provides a versatile mathematical-physical model to predict the optical and electromagnetic properties of metasurfaces. The application of mathematical functions in classical optical problems is a well-established phenomenon. For instance, in geometric optics governed by Fermat's principle and Snell's law, the surfaces of lenses and mirrors have spherical, parabolic, or aspherical shapes to focus light on a given spot. In laser optics, the characteristics of laser beams are characterized by mathematical functions, such as the Gaussian function, Bessel function, Airy function, and Hermite and Laguerre polynomials. [19-21] In addition, the dispersion curve of an anisotropic material is described by an ellipse. If one of the dielectric tensors were to become negative, the dispersion curve would become hyperbolic. Such materials are therefore called hyperbolic materials. [22,23] Because of the unusual dispersion curve, hyperbolic materials could be used in super-resolution imaging as well as enhancement of spontaneous emission. In this review, we focus on the applications of catenary functions in optics and electromagnetics. There are two types of catenary functions, the hyperbolic cosine function (ordinary catenary) and the logarithmic cosine function, which is often called catenary of equal strength. [1] As shown in Figure 1, both curves resemble the parabolic curve for vanishingly small x values. As x increases, the discrepancy increases and the slope of the catenary of equal strength is the largest among the three curves. Like the parabola, both types of catenary functions Catenary functions play pivotal roles in describing the electromagnetic vectors, intensity distribution, and dispersion of structured light on the subwavelength scale. In this article, the history, basic theories, functional devices, and applications of catenary functions in optics and electromagnetics are reviewed. First, the catenary fields generated by the coupling of evanescent waves are discussed, together with their applications in flat optics, super-resolution imaging, and lith...

“…With the rapid development of nanofabrication technologies and gradually mature metasurfaces design strategies, we hope this problem will be solved in the near future. Furthermore, by utilizing the DMD to generate time sequence beams to selectively excite the corresponding sub meta holograms, dynamic display with 2 28 different holographic images and an extremely high frame rate (9523 frames per second) in the visible range have been demonstrated [118]. The proposed method provided an alternative method to achieve dynamic display.…”

Holography has attracted tremendous interest due to its capability of storing both the amplitude and phase of light field and reproducing vivid three-dimensional scenes. However, the large pixel size, low resolution, small field-of-view (FOV) and limited space-bandwidth of traditional spatial light modulator (SLM) devices restrict the possibility of improving the quality of reconstructed images. With the development of nanofabrication technologies, metasurfaces have shown great potential in manipulating the amplitude, phase, polarization, frequency or simultaneously multiple parameters of output light in ultrashort distance with subwavelength resolution by tailoring the scattering behaviour of consisted nanostructures. Such flexibilities make metasurface a promising candidate for holographic related applications. Here, we review recent progresses in the field of metasurface holography. From the perspective of the fundamental properties of light, we classify the metasurface holography into several categories such as phase-only holography, amplitude-only holography, complex amplitude holography and so on. Then, we introduce the corresponding working principles and design strategies. Meanwhile, some emerging types of metasurface holography such as tunable holography, nonlinear holography, Janus (or directional related) and bilayer metasurfaces holography are also discussed. At last, we make our outlook on metasurface holography and discuss the challenges we may face in the future.

Holography, with the capability of recording and reconstructing wavefronts of light, has emerged as an ideal approach for future deep-immersive naked-eye display. However, the shortcomings (e.g., small field of view, twin imaging, multiple orders of diffraction) of traditional dynamic holographic devices bring many challenges to their practical applications. Metasurfaces, planar artificial materials composed of subwavelength unit cells, have shown great potential in light field manipulation, which is useful for overcoming these drawbacks. Here, we review recent progress in the field of dynamic metasurface holography, from realization methods to design strategies, mainly including typical research works on dynamic meta-holography based on tunable metasurfaces and multiplexed metasurfaces. Emerging applications of dynamic meta-holography have been found in 3D display, optical storage, optical encryption, and optical information processing, which may accelerate the development of light field manipulation and micro/nanofabrication with higher dimensions. A number of potential applications and possible development paths are also discussed at the end.
