“…As metasurfaces comprise a rapidly growing field of research, there have been a few good review articles focusing in different areas [25][26][27][28][29][30][31]. Here we provide our perspective on this research field by reviewing the progress during the past few years, where metasurfaces are broadly defined as planar metamaterial structures with subwavelength thickness, operating at wavelengths ranging from microwave to visible.…”

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.

“…For instance, the strong resonance electromagnetic reflection found in metafilms partially filled with asymmetrical split-ring arrays [11], in flexible metasurfaces [45] and in stereometamaterials [31] has offered the prospect of a multitude of applications as quantum optics [1] and negative refraction [13]. As another example of destructive interference in optics, two-photon interference can result in a total cancellation of the photon output because of the coalescence of the two single photons, which was first observed by Hong et al [18].…”

Phonon Interference and Energy Transport in Nonlinear Lattices with Resonance Defects

et al. 2015

We introduce and model a three-dimensional atomic-scale phononic metamaterial producing two-path interference phonon antiresonances to control the heat flux spectrum. We show that a crystal plane partially filled with defect-atom arrays causes a total phonon reflection at the frequencies determined by masses and interaction forces. Such patterned atomic planes can be considered as high-finesse atomic-scale interference phonon metamirrors. We emphasize the predominant role of the second phonon path and destructive interference in the origin of the total reflection in comparison with the Fano-resonance concept. The random defect distribution in the plane and the anharmonicity of interatomic bonds do not deteriorate the interference antiresonances. The width of the interference antiresonance dip can provide a measure of the coherence length of the phonon wave packet. All our conclusions

“…PI has attracted immense interest because of its extraordinary thermal, mechanical, and chemical properties. Particularly among the various flexible substrate, we selected Kapton ® for its excellent thermal stability, solvent resistance, low cost, electronic and mechanical properties including high Young's modulus (2.5 GPa), wide operating work temperature (−269 to 400 • C), high resistivity (1.0 × 10 17 Ω·cm), low coefficient of thermal expansion (20 ppm· • C −1 ), and low thermal conductivity (0.12 Wm −1 ·K −1 ) [17].…”

This paper presents the fabrication and characterization of a flexible gas sensor based on TiO 2 nanotubes membrane, onto which array interdigitated gold electrodes in one side and a common heater in the backside were obtained using conventional microfabrication techniques. This was used to detect hydrogen sulphide within a concentration range of 6-38 ppm. The response to low concentrations of H 2 S at low temperature and good stability make the sensor a promising candidate for practical applications. These results support the proposal that the TiO 2 nanotubes membrane flexible sensors are promising in portable on-site detection based on low cost nanomaterials.
