“…We should note here that the applications of optical metasurfaces in the general sense of the word (i.e., patterned thin layers on a substrate) go beyond spatial wavefront manipulation. Thin light absorbers [79][80][81][82][83][84][85][86][87][88][89][90][91][92][93], optical filters [94][95][96][97][98][99][100][101][102][103][104][105][106], nonlinear [107][108][109][110][111][112][113][114], and anapole metasurfaces [115,116] are a few examples of such elements. This review is focused on applications of metasurfaces in wavefront manipulation, and therefore it doesn't cover these other types of metasurfaces.…”

During the past few years, metasurfaces have been used to demonstrate optical elements and systems with capabilities that surpass those of conventional diffractive optics. Here we review some of these recent developments with a focus on dielectric structures for shaping optical wavefronts. We discuss the mechanisms for achieving steep phase gradients with high efficiency, simultaneous polarization and phase control, controlling the chromatic dispersion, and controlling the angular response. Then we review applications in imaging, conformal optics, tunable devices, and optical systems. We conclude with an outlook on future potentials and challenges that need to be overcome. A. High-efficiency high-gradient phase controlSince high-contrast transmitarrays (HCA) are central to the most of the discussions of this section, we first briefly discuss their operation. We are primarily interested in the two-dimensional HCAs, and therefore we consider their case here, although much of the discussions are also valid for the one-dimensional case. In general, these devices are based on high-refractive-index dielectric nano-scatterers surrounded by low-index media [13, 38, 65, 67, 70-72, 76, 78]. The structure can be symmetric (i.e., with the substrate and capping layers having the same refractive indexes) [36] or asymmetric [66,67,76,78]. Depending on the materials and the required phase coverage, the thickness of the high-index layer is usually between 0.5λ 0 and λ 0 , where λ 0 is the free space wavelength. Typically, these structures are designed to be compatible with conventional microfabrication techniques;

“…As an application, such selfcomplementary artificial surfaces have been used for efficient polarizers. 44,45 In the field of antenna design, it is known that a self-complementary antenna has a constant input impedance. 46 Therefore, self-complementary metasurfaces are expected to exhibit a frequency-independent response.…”

Plane-wave scattering by self-complementary metasurfaces in terms of electromagnetic duality and Babinet's principle

We investigate theoretically electromagnetic plane-wave scattering by self-complementary metasurfaces. By using Babinet's principle extended to metasurfaces with resistive elements, we show that the frequency-independent transmission and reflection are realized for normal incidence of a circularly polarized plane wave onto a self-complementary metasurface, even if there is diffraction. Next, we consider two special classes of self-complementary metasurfaces. We show that self-complementary metasurfaces with rotational symmetry can act as coherent perfect absorbers, and those with translational symmetry compatible with their self-complementarity can split the incident power equally, even for oblique incidences.

“…Other type of complementary MTSs has been investigated in literature; surface waves can be supported on self-complementary MTSs [16]. MTSs with complementary split ring resonators in different orientations exhibited either a band stop or band pass behaviour [17]. Checkerboard MTSs with adjacently connected patches, have been shown to support a quasi-Transverse Electro-magnetic (TEM) mode [18].…”

A complementary frequency selective surface (CFSS) can be formed on the basis of Babinet's principle. It consists of an array of slots separated from an array of dipoles by a thin dielectric substrate. This study shows that by adding an extra layer of dipoles to a CFSS capacitance can be added to the structure, which leads to a decrease in its resonant frequency. This new structure is called a dipole-slot-dipole metasurface (MTS) and it has unit-cell dimensions of l/10 × l/10 × l/333, where l is representing the free space wavelength. The dipole-slot-dipole MTS has been fabricated and measured. The study also reports on its equivalent circuit; and the effects of the length of the dipoles on the added layer and their alignment on the pass band resonant frequency of the dipole-slot-dipole MTS.
