A Tunable Metamaterial Absorber Based on VO₂/W Multilayer Structure

On the enhancement of light absorption in vanadium dioxide/1D photonic crystal composite nanostructures

“…Experimental reflection measurements are also carried out using an infrared microscope (Bruker Hyperion 2000) and the Fourier transform infrared spectrometer (Bruker Vertex 70) equipped with liquid nitrogen cooled mercury cadmium telluride and mid-IR source [40]. Additionally, several theor etical and experimental works in VO 2 -based structures have been reported in the literature which indicate utilizing of this material for a variety of applications such as sensors, absorbers and thermal information processing [41][42][43]. With these features as inspiration, we theoretically design a new hybrid nanostructure composed of VO 2 and a 1DPC to obtain enhanced absorption in the near-IR region.…”

A dual‐band and wideband omnidirectional circularly polarized antenna based on VO2

“…Therefore, 68 C is a jump point of the conductivity of VO 2 . VO 2 exhibits metal properties at temperatures equal to or greater than 68 C, and keeps insulating state at temperatures below 68 C, 11 which makes VO 2 widely used in designing the surfaces, 12 the absorbers, 13,14 and the antennas. 15,16 Since the insulator-metal transition of VO 2 , we can describe its physical properties by the conductivity.…”

Multifunctional Polarization Converter Based on Dielectric Metamaterial

“…Metamaterials offer new avenues for controlling the field vector, in the application of polarization control. [21,22] Based on this advantage, several metamaterial polarization conversions between the transverse electric E z -field (TE) and the transverse magnetic H z -field (TM), [15,23] left-handed circular polarization (LCP) and right-handed circular polarization (RCP), [24,25] or tunable devices [26] have been proposed; however, few have exhibited multifunctional characteristics and novel polarization conversion methods, except the birefringence or chiral media, have not been developed further.…”
