“…In the latter work, a linear phase gradient at wavelength of 633 nm was created by using six TiO 2 cylinder resonators of various diameters sitting on top of a silver plane ( figure 17(d)), demonstrating a deflection from the specular reflection by the expected 20 • (figure 17(f)) [21]. It was shown that considerable dissipation occurs within the TiO 2 resonators, partially because this configuration can also function as a metamaterial absorber [145]. Even more energy is coupled to surface waves, which could be useful and was described in a very recent theoretical proposal of directional launching of surface waves [146].…”

Abstract. Metamaterials are composed of periodic subwavelength metal/dielectric structures that resonantly couple to the electric and/or magnetic components of the incident electromagnetic fields, exhibiting properties that not found in nature. This class of micro-and nano-structured artificial media have attracted great interest during the past 15 years and yielded ground-breaking electromagnetic and photonic phenomena. However, the high losses and strong dispersion associated with the resonant responses and the use of metallic structures, as well as the difficulty in fabricating the micro-and nanoscale 3D structures, have hindered practical applications of metamaterials. Planar metamaterials with subwavelength thickness, or metasurfaces, consisting of single-layer or few-layer stacks of planar structures can be readily fabricated using lithography and nanoprinting methods, and the ultrathin thickness in the wave propagation direction can greatly suppress the undesirable losses. Metasurfaces enable a spatially varying optical response (e.g., scattering amplitude, phase, and polarization), mold optical wavefronts into shapes that can be designed at will, and facilitate the integration of functional materials to accomplish active control and greatly enhanced nonlinear response. This paper reviews recent progress in the physics of metasurfaces operating at wavelengths ranging from microwave to visible. We provide an overview of key metasurface concepts such as anomalous reflection and refraction, and introduce metasurfaces based on the PancharatnamBerry phase and Huygens' metasurfaces, as well as their use in wavefront shaping and beam forming applications, followed by a discussion of polarization conversion in fewlayer metasurfaces and their related properties. An overview of dielectric metasurfaces reveals their ability to realize unique functionalities coupled with Mie resonances and their low ohmic losses. We also describe metasurfaces for wave guidance and radiation control, as well as active and nonlinear metasurfaces. Finally, we conclude by providing our opinions of future developments in this rapidly developing research field.

“…Two families of metamaterial absorber (MA) configurations (with and without ground planes) are then quickly developed based on these two pioneering works. These metamaterial absorbers can operate at almost arbitrary frequency spectra ranged from radio frequencies, microwave and terahertz frequencies, to even optical frequencies [8][9][10][11][12][13]. Moreover, strategies for expanding the operating bandwidths of MAs, such as dual-band [14,15], triple-band [16,17], multiband [18,19], band-tunable [20,21], broad-band [22,23], and ultra-broad-band [24,25] designs, have also been reported in recent years.…”

Abstract-We analyze and discuss an ultra-compact metamaterial absorber (MA) by introducing meander lines into the resonant cells and covering another dielectric layer onto the MA. The size reduction procedures are presented step by step and an ultra-compact metamaterial absorber with in-plane (lateral) dimension of λ/28 and vertical thickness of λ/37 is obtained. We further present two variations of MA configurations which can reach similar ultra-compact sizes. The proposed ultracompact MAs show near-unity absorption under a wide range of incident angles for both TE and TM radiations.

“…[24][25][26][27][28] These provide a good foundation for the study of dielectric metamaterial absorbers. A perfect absorber via placing high-dielectric cubes on a metal plate was proposed by X. Liu et al 29 The perfect absorber achieves a single-frequency absorption in X-band. To further broaden the absorption bandwidth, it should be noted that there are two necessary conditions for an efficient absorption.…”

In this paper, we propose a band enhanced metamaterial absorber in microwave band, which is composed of high-permittivity E-shaped dielectric resonators and metallic ground plate. The E-shaped all-dielectric structure is made of high-temperature microwave ceramics with high permittivity and low loss. An absorption band with 1 GHz bandwidth for both TE and TM polarizations are observed. Moreover, the absorption property is stable under different incident angles. The band enhanced absorption is caused by different resonant modes which lie closely in the absorption band. Due to the enhanced localized electric/magnetic fields at the resonant frequencies, strong absorptions are produced. Our work provides a new method of designing high-temperature and high-power microwave absorbers with band enhanced absorption.
