That is a bottom Au layer preventing the penetration of the THz wave, a dielectric SiO2 layer to accommodate and absorb the incident wave, and a patterned Au structure array to select the resonant frequency. The electromagnetic response of TMA could be flexibly modulated when the structure is ...
This deformation in the height of the SRR-1 cantilevers creates a structural asymmetry (δ) along the z-axis of the metasurface sample. As a result, near-field coupling between the asymmetric structures excites a sharp and weak Fano resonance34,35,36,37 feature (at 0.58 THz, red curve...
The realization of metamaterial absorbers in THz frequencies allows more efficient energy harvesting for imaging and sensing to be performed in planar structures, which are suitable for integrated devices. For applications such as single pixel imaging or spectroscopy, two key figures of merit are the ...
One of the MEMS physical sensors that integrate with metamaterials is the infrared or THz radiation detector. Unlike the III-V or 2D material based photodetector, there are no electron-hole pairs generated in the MEMS-based radiation detector. Instead, the heat generated by the incident EM wave...
