“…In particular, the permittivity of NC materials could be tuned by changing some related parameters such as the core radius of NPs, filling fractions and the host medium 34 – 38 . As a result, when these materials compared with dielectric and superconductor materials, these materials could be an excellent candidate 9 , 49 , 53 . Notably, the inclusion of dielectrics with MM may have a limited contribution towards the tunability of PBGs that could lead to a limited role of PCs in many applications through this frequency region 9 , 53 .…”

“…Notably, the inclusion of dielectrics with MM may have a limited contribution towards the tunability of PBGs that could lead to a limited role of PCs in many applications through this frequency region 9 , 53 . Furthermore, the inclusion of superconductors could provide some peculiar properties for the resulting PBGs 49 . However, the special requirements of superconductors near extremely high temperatures appear to be a significant impediment to this idea.…”

We have theoretically demonstrated and explored the transmittance characteristics of a one-dimensional binary photonic crystal composed of metamaterial (MM) and nanocomposite (NC) layers. The NC layer was designed from silver nanoparticles (Ag-NPs) in a host material as Yttrium oxide (Y2O3). Using the transfer matrix approach (TMM), the optical properties of a one-dimensional binary periodic structure having MM and NC layers in the Giga Hertz (GHz) range were examined. The filling fractions of nanoparticles have been explored to see their effect on the effective permittivity of NC materials. Furthermore, the transmittance properties of the suggested structure were investigated at various incident angles for the transverse electric (TE) polarization. In addition to that, different parameters, such as the thickness of the MM layer, the permittivity of the host dielectric material, the filling fraction, and the thickness of the NC layer are also taken into account. We also discussed the effect of these parameters on the width of the photonic bandgap (PBG). With the optimum values of the optical parameters of NC layer, this research could open the way for better photonic crystal circuits, splitters, switches and others.

“…Metamaterials are artificial composite materials with a periodic arrangement of elements and remarkable physical properties that do not exist in natural materials. Welldesigned metamaterials exhibit excellent properties in many fields, such as mechanics [1][2][3][4], acoustics [5][6][7][8][9], optics [10][11][12][13], and electromagnetics [14][15][16]. Due to these special properties, metamaterials have been widely used in transportation [17,18], the automobile industry [19,20], aerospace [21,22], and other fields.…”

Based on the concept of component assembly, a novel star polygon-coupled honeycomb metamaterial, which achieves a collaborative improvement in load-bearing capacity and vibration suppression performance, is proposed based on a common polygonal structure. The compression simulation and experiment results show that the load-bearing capacity of the proposed metamaterial is three times more than that of the initial metamaterial. Additionally, metal pins are attached and particle damping is applied to the metamaterial to regulate its bandgap properties; the influence of configuration parameters, including the size, number, position, and material of the metal pins, on bandgaps is also investigated. The results show that the bandgap of the proposed metamaterial can be conveniently and effectively regulated by adjusting the parameters and can effectively suppress vibrations in the corresponding frequency band. Particle damping can be used to continuously adjust the frequency of the bandgap and further enhance the vibration suppression capacity of the metamaterial in other frequency bands. This paper provides a reference for the design and optimization of metamaterials.

Based on the transfer-matrix method, we theoretically explore the transmission and reflection properties of light waves in a one-dimensional defective photonic crystal composed of superconductor (HgBa2Ca2Cu3O8+δ) and semiconductor (GaAs) layers. The whole system is centrosymmetric and can generate a defect transmission peak in the photonic band gap. We study the effect of the temperature on the defect mode. Results obtained show that the defect mode shifts to the lower frequency regions as the value of the environmental temperature increases, and the resonance of the defect mode can be strengthened further as the number of periods increases. In addition, our findings reveal that the central wavelength of the defect mode increases with the increase in the environmental temperature and it presents a nearly linear relationship between the central wavelength of the defect mode and the temperature in cryogenic environments. Therefore, we can use the temperature response of the defect mode to detect the temperature. It is hoped that this study has potential applications for the development of cryogenic sensors with high sensitivity.
