Experimental demonstration of ultrasensitive sensing with terahertz metamaterial absorbers: A comparison with the metasurfaces

TL;DR: In this article, the authors demonstrate a metamaterial absorber based ultra-sensitive sensing scheme at the terahertz frequencies with significantly enhanced sensitivity and an order of magnitude higher figure of merit compared to planar metasurfaces.
Journal ArticleDOI

Multispectral terahertz sensing with highly flexible ultrathin metamaterial absorber

TL;DR: In this paper, a multichannel metamaterial absorber with the aim to be used as a label-free sensing platform in the terahertz regime is presented, where the topology of the resonators deposited on a thin flexible polymer by means of optical lithography is capable of supporting multiple resonances over a broad frequency range.
Journal ArticleDOI

Electromagnetically induced transparency control in terahertz metasurfaces based on bright-bright mode coupling

TL;DR: In this paper, a planar terahertz metamaterial (MM) comprised of three-gap split-ring resonators is proposed and implemented numerically to dynamically tune the EIT window by incorporating photosensitive silicon pads in the split gap region of the resonators.
Journal ArticleDOI

Ultra-flexible multiband terahertz metamaterial absorber for conformal geometry applications.

TL;DR: The use of single-sized "meta-cells" to achieve multiple absorption peaks and the use of a thin-flexible dielectric spacer makes it promising for stealth technology applications in order to disguise objects and make them less visible to radar and other detection methods.
Journal ArticleDOI

Tunable terahertz metamaterials with negative permeability

TL;DR: In this article, the authors demonstrate experimentally and theoretically dielectric metamaterials exhibiting a tunable range of negative effective permeability in the terahertz spectral region 0.2 -0.36 THz.
