Special Issue Information

Dear Colleagues,

Although man-made composite electromagnetic materials have been studied for more than one-hundred years, it was not until the beginning of the 21st century that the term “metamaterials” became a part of the photonics nomenclature. Since then, intensive research efforts have been devoted to the study and fabrication of such complex artificial engineered structures. While these efforts were initially fueled by the material property requirements of various theoretical predictions—such as negative-index perfect lenses or transformation-optics based cloaks—recent trends have shown that the field of metamaterials has much more to offer other than simply to satisfy the hunger for exotic optical properties. In this regard, metamaterials have proven to be a versatile tool to enable next-generation photonic technologies.

This Special Issue invites manuscripts that introduce recent advances in the area of “Optical Metamaterials and Metasurfaces”. All theoretical, numerical, and experimental papers are accepted. Topics include, but are not limited to, the following:

  • Reconfigurable and programmable metamaterials and metasurfaces;
  • Quantum and superconducting metamaterials;
  • Metamaterials for nanoelectronics, nanophotonics and nanoantennas;
  • Nonlinear metamaterials and metasurfaces;
  • Tunable metamaterials and metasurfaces;
  • Space–time modulated metamaterials;
  • Chiral, toroidal and magneto-optic metamaterials;
  • Nonreciprocal and topological metamaterials;
  • 2D materials and metamaterials;
  • Analytical and numerical modeling of metamaterials and metasurfaces;
  • Fabrication and experimental characterization of metamaterials.

In this paper, a five-band metamaterial absorber with a tunable function in a terahertz band is proposed, which consists of a gold grounding layer, a polyimide dielectric layer, and a periodic patterned graphene layer. The patterned graphene layer is constructed from two sets of copper-coin-shaped structures of different sizes. The designed absorber achieves absorptions of 96.4%, 99.4%, 99.8%, 98.4%, and 99.9% at 4.62 THz, 7.29 THz, 7.70 THz, 8.19 THz, and 8.93 THz, respectively, with an average absorption intensity of 98.78%. The physical mechanism of this five-band absorber was explained by the impedance matching principle and electric field distribution. The absorption performance of the five-band absorber can be effectively tuned by changing the geometry of the patterned graphene array and the thickness of the dielectric layer. Given that the resonant frequency of the absorber varies in proportion to the Fermi level, by varying the Fermi level of the graphene hypersurface, we can achieve the continuous tuning of the absorption performance over a wide frequency range. The five-band absorber has a stable absorption performance over a wide incidence angle of 0–65°, and by combining the merits of high absorption, dynamic adjustability, and a large number of absorption peaks, the given absorber could have great potential for applications in nondestructive testing, imaging, communication, sensing, and detectors.
