Special Issue Information

Dear Colleagues,

On-chip photonic integrated circuits (PIC) have attracted widespread interest due to their many potential applications, such as absorption spectroscopy, biological and chemical sensing, and free-space communications. Among these applications, photonics and metamaterials have recently offered a strategy to artificially control electromagnetic waves on the subwavelength scale and obtain unique optical response due to their extraordinary properties that cannot be found in traditional materials. With the rapid development of photonics and metamaterials, they could be applied in many fields, such as cloaking devices, thermophotovoltaics, microfluidic chips, biomedical sensors, displays, optical communications, and so on. Current photonics and metamaterials provide an effective approach to perform specifically electromagnetic functions using passive or active manipulations enabling novel breakthrough applications.

This Special Issue aims to gather high-quality research contributions dealing with photonics and metamaterials devices spanning the whole electromagnetic spectrum to figure out extraordinary optical characteristics for future optoelectronics integration. The current state of this exciting research field will be presented, covering a wide range of topics including, but not limited to:

  • A bottom–up approach toward metamaterials and plasmonics;
  • Advanced passive and active photonics and metamaterials;
  • Novel designs and applications of nanophotonics, metamaterials, metasurfaces, and metadevices;
  • Nanophotonics and metamaterials based on graphene and related 2D materials;
  • Structural or functional materials and devices for lighting, displays, and imaging applications;
  • Light shaping using photonic integrated devices;
  • Plasmon-induced hot carrier: fundamentals and applications;
  • 3D printing for photonics and metamaterials applications;
  • Nonlinear metasurfaces and plasmonics;
  • Wave propagation in acoustic and elastic metamaterials: novel design and practical applications;
  • Transformation optics and other waves: novel physics and practical applications;
  • Bio-engineered metamaterials and plasmonics.

A conformal metamaterial absorber with simultaneous optical transparency and broadband absorption is proposed in this paper. The absorptance above 90% over a wide frequency range of 5.3–15 GHz can be achieved through topology optimization combined with a genetic algorithm (GA). The broadband absorption can be kept at incident angles within 45° and 70° for TE mode and TM mode, respectively. In the meantime, by employing transparent substrates, including polyvinyl chloride (PVC) and polyethylene terephthalate (PET), good optical transmittance and flexibility can be obtained simultaneously. The experimental results agree well with the numerical simulations, which further validates the reliability of our design and theoretical analysis. With its visible-wavelength transparency, flexibility, broadband absorption, low profile, excellent angle stability and polarization insensitivity, the proposed absorber is highly favored for practical applications in microwave engineering, such as electromagnetic interference and stealth technology. Moreover, the proposed design method of topology optimization can be extended to design the absorber quickly and efficiently, according to specific engineering requirements. Full article

This paper presents a full electromagnetic (EM) characterization of metallic lenses. The method is based on the utilization of free-space transmission and reflection coefficients to accurately obtain lenses’ tensorial EM parameters. The applied method reveals a clear anisotropic behavior with a full tensorial directional permittivity and permeability and noticeably dispersive permeability and wave impedance. This method yields accurate values for the effective refractive index, wave impedance, permittivity, and permeability, unlike those obtained by simple methods such as the eigenmode method. These correct cell parameters affect their lens performance, as manifested in a clear level of anisotropy, impedance matching, and losses. The effect of anisotropy caused by oblique incidence on the performance and operation of lens designs is illustrated in a lens design case. Full article

Looking back on the development of metamaterials in the past 20 years, metamaterials have gradually developed from three-dimensional complex electromagnetic structures to a two-dimensional metasurface with a low profile, during which a series of subversive achievements have been produced. The form of electromagnetic manipulation of the metasurface has evolved from passive to active tunable, programmable, and other dynamic and real-time controllable forms. In particular, the proposal of coding and programmable metasurfaces endows metasurfaces with new vitality. By describing metamaterials through binary code, the digital world and the physical world are connected, and the research of metasurfaces also steps into a new era of digitalization. However, the function switch of traditional programmable metamaterials cannot be achieved without human instruction and control. In order to achieve richer and more flexible function regulation and even higher level metasurface design, the intelligence of metamaterials is an important direction in its future development. In this paper, we review the development of tunable, programmable, and intelligent metasurfaces over the past 5 years, focusing on basic concepts, working principles, design methods, manufacturing, and experimental validation. Firstly, several manipulation modes of tunable metasurfaces are discussed; in particular, the metasurfaces based on temperature control, mechanical control, and electrical control are described in detail. It is demonstrated that the amplitude and phase responses can be flexibly manipulated by the tunable metasurfaces. Then, the concept, working principle, and design method of digital coding metasurfaces are briefly introduced. At the same time, we introduce the active programmable metasurfaces from the following aspects, such as structure, coding method, and three-dimensional far-field results, to show the excellent electromagnetic manipulation ability of programmable metasurfaces. Finally, the basic concepts and research status of intelligent metasurfaces are discussed in detail. Different from the previous programmable metamaterials, which must be controlled by human intervention, the new intelligent metamaterials control system will realize autonomous perception, autonomous decision-making, and even adaptive functional manipulation to a certain extent.
