The application of metamaterials in controllable thermal emission devices is an interesting field. However, most of the demonstrated thermal emitters require continuous consumption of external energy (electrical or thermal) to provide an effective thermal emissivity. Here, a metamaterial containing phase change material GST and shell material with controllable thermal emission power is proposed and measured. Based on the GST layer being in a completely amorphous state, this metamaterial can achieve an emissivity of 0.212 at wavelength 7.11. When GST is in a crystalline state, the metamaterial can obtain a thermal emission band (with an average amplitude of 0.857 and a bandwidth of 6.16). This metamaterial can achieve a switching effect of thermal emissivity based on the phase transition characteristics of GST. In addition, due to the fact that the GST layer can obtain numerous intermediate states between completely amorphous and crystalline states, this metamaterial can excite numerous thermal emission states by changing the temperature. This thermal emission characteristic provides a foundation for the development of functionally rich thermal emitters. The measurement results indicate that this metamaterial thermal emitter can achieve temperature sensitivity . By increasing the thickness of the GST layer, the thermal emission performance of the metamaterial can be enhanced. In addition, shell materials provide the fundamental thermal emission performance of this metamaterial. Since the phase transition of GST does not require the continuous consumption of external energy, the metamaterial has the potential to be used in the development of low-power heat emitters, as well as temperature sensors.

“…With the development of processing and measurement technology, many sensors with novel resonance performances have been reported, such as temperature sensing, gas sensing, liquid sensing, biosensors, blood sensing, and so on. [16][17][18][19][20] These sensors are mainly based on the principle that the resonance properties (absorption or transmission and reflection) of metamaterials or metasurfaces are changed due to the refractive index of the environmental medium. The sensing information of environmental media, especially gas sensing and liquid sensing, is obtained based on these changes in resonance performance.…”

Metamaterial absorbers are widely used in the sensing field based on their rich resonance behaviors. So far, the applications of metamaterial absorbers in gas sensing have not been paid much attention by researchers. A single-mode narrow bandwidth THz metamaterial absorber is suggested and validated. An absorption peak is excited based on local surface polarization mode resonance and dielectric loss in the 2 to 36 THz band. In experiments, the hole array diameter R is increased, the absorption peak is increased from 0.51 to 0.66, and resonance position is moved to the high-frequency region. When the dielectric layer thickness h 2 is increased, the absorption peak is increased from 0.51 to 0.57, and resonance position is moved to the low-frequency region. Similarly, when the dielectric layer thickness h 3 is increased, the absorption peak is increased from 0.51 to 0.53, and resonance position is also moved to the low-frequency region. This metamaterial absorber exhibits the feasible for gas and liquid sensing.

One of the most interesting topics in bio-optics is measuring the refractive index of tissues. Accordingly, two novel optical biosensor configurations for cancer cell detections have been proposed in this paper. These structures are composed of one-dimensional photonic crystal (PC) lattices coupled to two metal–insulator–metal (MIM) plasmonic waveguides. Also, the tapering method is used to improve the matching between the MIM plasmonic waveguides and PC structure in the second proposed topology. The PC lattices at the central part of the structures generate photonic bandgaps (PBGs) with sharp edges in the transmission spectra of the biosensors. These sharp edges are suitable candidates for sensing applications. On the other hand, the long distance between two PBG edges causes that when the low PBG edge is used for sensing mechanism, it does not have an overlapping with the high PBG edge by changing the refractive index of the analyte. Therefore, the proposed biosensors can be used for a wide wavelength range. The maximum obtained sensitivities and FOM values of the designed biosensors are equal to 718.6, 714.3 nm/RIU, and 156.217, 60.1 RIU−1, respectively. The metal and insulator materials which are used in the designed structures are silver, air, and GaAs, respectively. The finite-difference time-domain (FDTD) method is used for the numerical investigation of the proposed structures. Furthermore, the initial structure of the proposed biosensors is analyzed using the transmission line method to verify the FDTD simulations. The attractive and simple topologies of the proposed biosensors and their high sensitivities make them suitable candidates for biosensing applications.
